    <font color=purple> As some of you may know, I'm in the process of redoing my interior. I pulled back the carpet and found that the previous owner did a repair job on the rear area around one of the body mounts. As you may also remember, I will be putting in a 2" body lift and now I need to fix this area first. My question is : What is the best way to do this ? I went to a local junkyard today and they have a blazer there that has the same problem except the area right below the rear seat is fine, Can that peice be used for the area by the body mounts ? They said to cut that out it would cost me $50. I was wondering if it would be better to just get the whole rear peices from LMC instead ? Or what ? I've never done this type of repair before so I want to learn from you guys. I know if I take it somewhere they'll kill me on the cost to repair. I want to get going on it as soon as the weather lets me get outside so fast replies would be appreciated. I want to get the work done by Spring so I can enjoy it all Summer long without having to tear it all apart. Once I get past this little repair I should have no problem with the rest of it. Thanks Guys/ Gals.

    <font color=purple> Here's a pic of the area I'm talking about. Notice the patch put in by previous owner by the driver's side wheel well hump. It looks to be riveted on there and it's humped up where the body bolt is.

    Can I just cut out the whole area and weld in some stock steel then drill out for the body bolts .......... I don't know.

    Sorry Riz, I'm no body man but I have a couple small spots and will evenually need to do something also. I want to keep my truck for a long time and will probably go for the new metal from LMC or? If you have some good body shops in the area, go talk to them. Estimates are free and you can usally dig some info out of them. You also might want to talk to some welders about a price to set it then finish it off yourself. Sorry I can't be of more help but someone out here must have done it. Keep bringing it to the top until you get a real anwser.

    You could either buy a complete rear floor section, but it is rather costly(around $450).. Or you could buy sections of the floor and put them in yourself or have someone put them in.
    LMC offers the rear section from about center wheel wheel back and they come in two sections @$70ea. side. This is just the floor pan and does not have wheel wells. I imagine they would have the front floor section also that these 2 panels wouldn't cover. I would see if there is any local shops, because i think you could get those panels cheaper.

    Wish I could help but I've never looked specifically at those areas of the tub with that in mind. The only thing I can say is look at it and see if the support ribs are the same. If they are, you should be able to splice it in back there without too much trouble. However, I think the rib depth is different due to frame arch. In any case, the spot repair is going to be allot easier and cheaper than the full floor. If you take some measurements, you might be able to find some place to cut out a solid floor section (at a junk yard) that can be easily modified to fit where you need it. You might even find a piece of a (pickup) bed floor that will work. Wish I could help more but this is how I would approach the problem...

    Well better late than never here riz but i'll through in my $.02. The GM floor is available, I priced one out and it only runs about $375 from the Chevy dealer in town. I went down there during the winter to pick my parts man's brain and told me he had something in back someone ordered that I might like to see. Well, lo and behold a whole freakin' bed floor! This sucker is tight. Its ALL there, the tailpan, galvanized metal, and a lifetime warranty. If you bought both halves through LMC you're looking at $140. Not to mention the fun of trying to salvage the tailpan and if yours is bad than thats another $150 for it. A possible grand total $290, $85 more dollars doesn't sound to bad for a piece that will fit flawlessly, is all assembled, and comes with a lifetime warranty. I have mine on order and next Monday it should be in my hands [​IMG].

    <font color=purple> Awesome ! Can you give me part #'s ? I'd still be interested in going that route ........ I'd love to have the whole area replaced......... I've got tax money that would pay for it easily. Once again, please give me any info on this so I can take it to my Chevy Dealership this week. Thanks

    The number is 15571692 PANEL ASM 16.545 .....basically those first numbers are what you want. You can get it through gmpartsdirect.com but I definetely prefer the dealer route because its keeps business in town, you have an actual person to talk to, and god forbid, warranty incidents are easier. The list price is $563.13 but I pulled mine in for $371.67. It is a pretty sweet piece of metal. There may be a little shipping damage you'll have to deal with (seems like there is on EVERY body panel, just part of life). This unit should just bolt right on it. Take out the row of 1/2" bolts up front, the body mounts, the fuel pipe cover, the tailgate, and some bolts in the corner of the tailpan near the brake lights. Then I suppose you could put some corroless or what not on top your frame while you're "in the neighborhood" and go heavy with the seam sealer on the edges when you drop the piece in. I am so stoked for this summer because Im putting that piece in and at this moment my 12-bolt is in the garage disassembled. Looks to be in good shape, putting in new seals and swapping in a new axle shaft because one is pitted where the bearings ride. Hmm, I wonder if 3.73s will be better than 3.08s?

    <font color=purple> Holy Crap ! I had to go out 44 pages to find the post I was looking for ! I could get anything with a search. Hey Balzerboy, did you get yours yet ? Please post pics of it so I can see what it looks like. Does it come with the tailpan ? I'm thinking of going that route instead of having a local guy weld up the problem areas ....... It would cost me more to do it that way anyhow. I want to see pics of what it looks like and instructions on how to install it.

    Hey Mikey, Could you check and see if you can get it any cheaper from where you work, I think you said something about that earlier. I'd appreciate it if you could look into it for me.

    I'll post pics later tonight to show you what I found today while tearing into the rear .........

    SO blazer boy, are you saying that they still make the whole rear floor, or were you just lucky and found one laying around?? Just wondering.

    <font color=purple> They still make the whole rear floor ....... It's GM part # 15571692 ........... I'm leaning toward that route versus patching a lot of areas.

    oh sweet riz, so you KNOW they still make it?? I thought I heard from my parts guy around here they didn't, but that was when I first got the truck and was only 15, so they tell us kids anything to get us outta the stores. But I'll try again. Where are you at, so if they say no, I can tell them that your GM dealer can get them. Thanks and keep in touch.

    <font color=purple> I was just going to post the GMPARTSDIRECT.com address .......... I'm looking at getting from them as my local dealership quoted me at $450.00 and GMPARTSDIRECT.com would save me $113.00 smackers ! The dealership can get me one in a week so if it's quicker that way it would be worth it. I live about 15-20 mins out of the Twin Cities in a town called Hudson. WI ......... I was told they could get me the rear section already.
