    I just finished installing my 91 suburban grille conversion on my 88. It was a pretty long process; I logged about 10 hours doing the whole conversion by myself. I used the original wiring harness and spliced in the 91 pigtails- I soldered the splices, used heat shrink tubing and then electrical taped them; they SHOULD hold up well. Since I had to pull the radiator and had the core support available, I installed a B&M tranny cooler as well and changed the tranny fluid/filter.

    I was less then impressed with the taiwanese repro grille and headlight bucket crap. As a matter of fact, I was pretty disgusted. I had to dremel quite a bit around the grille to even get a decent fit, and the buckets and grille don't line up very well. At first I thought it was just how it was stock, but when I test fit the original trashed GM pieces, they went together a lot better. I would have to recommend to anyone wanting to do this to go OEM grille and buckets, even if it's used.

    Here it is! I could SURE use the grille emblem if anyone has one lying around. Please PM me; I will buy it from LMC truck otherwise.

    My next project-

    [​IMG]

    And then the Doug Thorley headers and I am calling it quits for a while... By the way, I have been working with Doug Thorley's tech support, they are amazing. I sent them some pictures of the engine compartment, their R&D team looked at my setup and gave their recommendation within an hour. They have a special on the headers and y-pipe right now for $450 directly from Thorley. On the system I ordered, the y-pipe is even made for a 4-6" lifted truck! The tech's name is Sean Crary. Awesome guy! Those Thorley header's are 14ga steel! and have 3/8" flanges! Those are the sturdiest ones out there.

    Sean mentioned on a stock TBI motor to expect 20 lb/ft at 2100 RPM with a slightly faster torque delivery as well. I heard the tri-Ys are good for torque and good balance of a short and long tube design.

    Truck looks so natural, looks great. Thanks for warnings on Taiwan stuff. I installed an LMC grille and HL rings; they're good enough, fit, and the right price.
    Thats one outsatnding rig you're building!:bow:

    Let me know if the OEM emblem fits in that grille. The aftermarket grilles I looked at were like yours with only the square recess not the oem bowtie shape so my emblem wouldn't fit in them. I ended up using the used grille I picked up for that reason.

    Just for you, I took a few pics; The reman grille obviously doesn't have the inlet for the emblem, however the emblem still looks pretty good and goes over the square recess ok. I did have to dremel the square recess; it was too high and was holding the emblem away from the grille. I took a few pics to document-

    Pic of emblem over square recess pre-dremel; Note the gap between the emblem and grille. Not too fancy...

    This is the square recess post dremel-

    I'm thinking about putting one on myself. Might have saved my new H3 from a stone chip, just off my 80 mph line of sight.:doah:

    You wanna see how ugly mine looks now without it?
    It has chips and cracks all over the windshield, and the bugs are so hard to clean.
