Camaro Subframe Alignment Pin Dimensions

[rsgt]

There is a hole at the front of the rear frame rails just in front of the front leaf spring mounting bracket, use this hole to cross measure to the lower front ball joint grease fittings. When you have both measurements the same the subframe will be square to the body.

I always used old lug wrenches.

I think this good way to get it straight.

I just reinstalled my sub frame and I used the holes in the bottom at the front of the rear frame and the locating holes at the firewall on the subframe....assy manual says they should be 76" cross measurement each side. As another check I used the rear edge of the very front core support bolt hole and measured across to the center of the top fender bolt on each side..again going from driver side to pass and pass side to driver and got it within a little less than 1/8" difference on each measurement so I was good to go. I think the factory used +/- 1/8" or +/- 1/4" Either way, they didn't get them as close as we do now. It really wasn't as hard as I thought it was going to be.

My post got lost in the missing post SNAFU so I'm just adding it again.

5/8" is too big for the alignment pins. The speck in the factory assembly manual of .610 +0/-.002 is pretty close. I had to go just a wee bit under that on my drivers side but it worked fine on my passenger side.

I haven't run a cross measurement yet but everything is looking pretty good.
