Frame off: Body mount alignment

[SStavin]

Wrapping up a frame swap/frame off project with some new Energy Suspension mounts. I have a question for the experienced here as I'm having a hell of a time getting everything aligned and bolted together. What tips/tricks do you have to align the mounts with the body side cage nuts?

I used 4 longer body bolts in the 4 locations just in front and behind the C channel so I could hang the frame and move it into place, then installed the body bolts while I measured and measured and measured to make sure the body was sitting straight on the frame. I didn't have the rear end, suspension or engine installed and had the body on axle stands and lifted the frame to the body.

Agreed with what GP said....use a few longer bolts to guide the frame close enough. Then measure until you hate a tape measure buy using the same point on both sides of the body fore and aft. Once all the bolts are threaded, but not tight, check the measurements again, then snug them side to side in an "X" pattern as to not pull the body by accident.
I was able to get my cutlass within an 1/8" in most places side to side and front/back which was acceptable for me.

Btw, can you give us a little more info on that monte? Looks like a nice resto going on with an LS tucked in. Welcome to forum from KY.

Great advice guys thanks much. I love "measure until you hate the tape measure." I have a pretty lengthy build thread going over at montecarloss.com http://www.montecarloss.com/community/ubbthreads.php?ubb=showflat&Number=895848#Post895848

Don't rush putting the body and frame together. If you ever want to run wider tire in the rear if the frame isn't on straight and even it could cause you problems. And don't forget the anti seize on the body bolts

No problem.man, that's what this place is all about...helping a fellow gearhead! I just checked out you're build thread, nice! It's crazy my 87 cutlass has went through a similar transformation like yours. Stock 307 to a carbed 355sbc, then upgraded to the stealth ram, tore it apart to do the resto, got it running and block took a crap, pulled the drivetrain to send off to paint, and i recently acquired a 5.3 LM7 that will be going back in with twin hair dryers and a 4l80 of some sort.
Here is the link to my thread here....

Definitely will. I love mcss.com but it's a bit slow lately.

Welcome to the site from Houston. Cool project!

I just binge-read your entire thread. Cool build! That's going to be a fun car to drive. That rust was bad. Thanks for saving another G-Body from the cancer.
