    i took out a rivit out of my crossmember and it was all smudged looking.like someone smeared the rivit(rivit was stretched and stuff and wasnt straight anymore)...now the holes dont line up, i tried to turn my wheels left and right, put a wheel up on something hoping my frame would flex enough so the holes would line up. i know other people had problems like this..just wondering what you guys did to make the holes line up so i can stick a bolt in there?

    Could you just drill the holes out bigger and put a bigger bolt in there?

    That's what I'd so. Be sure it's a high strength bolt.

    One day I'm going to get bored and go at my frame with an air chisel, torch, bolts, and a welder and eliminate as many rivets as possible....

    drive a drift punch in the hole, clamp it with a c clamp then remove the punch and replace with a bolt.

    drill it 3/8" of an inch and get 3/8" boilt

    done, and if you have access to a welder then weeld everything up to prevent extra flex, if its bad, i guess that depends on where how you drive truck

    good luck

    I'd say you're going to use a 7/16" or 1/2" bolt in a hole that you took a rivet out of. Use a grade 8.

    You'd have to drill a pretty big hole to put a 3/4" bolt in.

    When I converted my 4wd to 2wd, most of the rivets I had to replace were 3/8"

    If you really want to get fancy, after getting the two holes lined up, you can tap it. Between the two pieces of metal I was able to get about two threads. Probably doesn't help much strength-wise, but tightening the HECK out of the nut is a lot easier that way, and so was getting them lined up when I released the clamp.

    I took EVERY rivit out of my frame and replaced them with 3/8 (where appropriate) grade 8 bolts and tightened the snot out of them. I do truck pulls and since then have broken axles, transfercase adapters, motor mounts, etc. and the frame hasn't even shifted (I used a grease-pen to mark seems to see IF it would shift and it didn't). I didn't get a chance to pull last year, but I'm heading into this year with a BBC instead of the built small block, so I will see if that has any effect on the bolts.

    i used drift punch to line up the holes, then jammed a piece of pipe in between my frame rails to push my frame apart and keep it in place. Then i drilled and tapped it, stuck a grade 8 bolt, lock washers, nylock nut thing, and lotsa locktite.Thanks again
