    when i repainted my 88 i pulled up the carpet and found the same problem...i just welded it all back together and reinforced around the bolt holes for the seats...as far as i can tell its fine now and its been about 2 years...

    Loose some weight damn it, haha. I've only seen late model Blazers do this, I can't figure out, unless its just coincedence.

    strengthen your frame up a bit by boxing it or by adding crossmembers and triangles to it. but weld up the cracks also.
    new bushings might help after the repair but i doubt it. and get a more flexible suspension. take the stress off your frame a tiny bit

    I had those too. Can't weld them shut, you'll burn through the floor. I brazed them though.

    I as thking bondo or jb weld lol.
    Oh well... what would be a more flexible suspension.. i have really stiff shocks now... RS5000, I was thinking of getting some other ones... and single shocks in the back isntead of 2 or something like that.. and some edelbrock shocks although they are very xpensive

    First of all, you need to stop drill those cracks. Then you need to remove any loose rust with a wire wheel of some sort that will also take the paint away. Then you need to get a piece of 1/8 angle iron or something to that effect. Lay it down and mark your holes. Then drill the holes out so that your seat bolts wil go through the angle iron adn hold it straight and tight. Then you weld or get someone lese to weld that 1/8 angle iron to the floor where it is long enough to over lap the 2 under cab supports. then tack all the cracks up real good "without" burning through the floor.
    The part where you have hte most problem with burning through the floor is where you weld the thinner floor part to the 1/8 angles iron. If you can weld just make sure you have the wire pointing more into the thicker material piece than the thinner floor. And space the tacks out really good and allow ample time for the metal to cool. Then coat with some good undersoating that has rust suppression and sound proofing. They sell it at AutoZone. Then layout your insulation and then the carpet or floor mat, what ever you have. You will notice a hell of a difference in the stiffness of your seat. TRUST ME and I only way 170 lbs.

    Still hoping the GOV'T will ban the use of loud stereos with RAP music. [​IMG]
