Im about ready to put my rear end back in and realized all the control arm bolts are not the same.Iv got 6 that are 4 1/16 long and two that are 4 5/16 long , Where do the longer ones go? I think they must go on the upper arms just not sure if they go to the crossmember or the rear end.Iv also got the lower frame braces,if that helps at all.Oh ya ,this is for a 1969 12 bolt el camino.Thanks.:beers:

Do two of the bolts have a flange on the head?

I just bought 1/2 inch grade 8 bolts and nylock nuts from Home Depot to replace mine for a new rear end. They are all 4 inches long.

Yes,the two longer ones do have the flange on the heads,any idea where they go?

Unless someone else chimes in, I'll try to run out to the garage and take a look when I can.

The ones with the flange/washer head attach the front of the lower control arm.

If I'm using grade 8 bolts instead of factory bolts, should I use washers on all the bolts or just those two?

Kieth,thank you much.

Jay,I would use washers on all of them,couldnt hurt

This is correct.
