sub frame question

i am getting ready to put the subframe back in my car and need to know what i can use to line it up its a 72.

There are alignment tabs to get you close. Measure diagonally to make sure it's square. I like to use the sway bar mount holes on the front subframe to the forward leaf spring mount holes.

thanks thats what i was looking for .

Good call, Max. And I think they are 5/8" holes, brownie. Theres a post on here with a frame alignment diagram if youll do a search. Or I can email it to you if you want it. It may help some too.

I used wood dowells. They were a tight fit and didn't allow it to move. I got it within 3/16th of square.

Also remember to put the thick washer in correctly. It will mess you up with out it.

I used long 1/2" socket extensions, got me close, then I measured.

With a new set of aftermarket rubber mounts I had to leave the washer out.

MI wil give that a try also its been to cold to go out in the garage the last few nights i will fire the heater up over the weekend and get it done.

Why would you have to leave the washer out of the new rubber mounts? Just curious because next week i am gonna be putting my front sub-frame back on. Also do you know where I can find that Alignment Diagram here on Steves?

Thanks, Howard :chev:

My new mounts were slightly thicker. With the new mounts and no washer (the extra 1/4" thick one between the rubber and body) my fenders lined up perfectly
at the door.

Thanks for the diagram and info I had heard that you have to becareful about aftermarket body bushing because of a line up problem. But I wasn't sure what everyone meant by it. Thanks for explaing it.

Thanks again, Howard :chev:

Would anyone happen to have the frame diagram for a 70?

Thanks,

Joe

At the bottom of the one in the post it says 73-70 Nova. Also it should be the same for 69-74. The bushings just changed a little in 73 and 74 not the actual alignment.
