72 Nova sub frame repair

HI all. I have a 72 Nova sub frame that needs to have the body mount holes that mount the fire wall area of the body to the sub frame. The ones there are rusted and now much larger than what they should be. I have welded 1/4" plates opver the original metal and now i need to cut the correct size and location into the new plates. Does anyone have the proper dimensions for these body mount holes. I have new POLY mounts that will tell me what size the holes should be but they must be exact so the body and frame are correctly aligned. Please help me so i can start re-assembling the car.

If you don't get an answer here, you might try www.stevesnovasite.com/forums , or maybe www.camaros.net/forums (1st-gen Camaros use the same subframe as the '72 Nova).

That mount may have an extra hole that's used for alignment. I can't vouch for it personally, but I have heard it more than once.

I hope you welded the new plates at the original "level" of the old metal... Welding them on top will alter the mounting height of the subframe to the body and you will have a tough time getting body panels to fit correctly. I know 1/4" doesn't sound like much but, when you do the math, it will lower the bumper height by roughly 1/2". This will not be good when you are trying to put the fenders and hood back on... I just used approximations in my calculations so the number may be more or less then my example.
And, to answer your hole location question, measure from the rear cradle bolt holes on the body to the mid-mount holes at the firewall. You may notice the cradle has slots instead of true holes to allow for alignment during assembly. If you match the slot sizes you should be good.

You can buy a kit that comes with all 6 plates with the holes already there. Some people just weld the plates on top of the existing frame, rather than cutting out the old metal, but that will raise the body by the thickness of the metal. You would have to do all 6 together that way to keep it straight. There are also body drop bushings available.
