I have a 1949 1/2 ton that I've been working on since I was 14. Unfortunately, I've spent more time fixing someone else's mistakes as I bought it already clipped. I'm getting ready to do the last big job: installing a new subframe.

Currently it has a 76 front clip, and as some may know, it's very wide. Plus, the genius who put it on before didn't bother to center it (it's off by1/4") and didn't put the right spacers in. My truck has airbag suspension, and to get BARELY adequate turning clearance for the 18" wheels I have to put 120 PSI in the bags: it rides like a tank!

So I'm looking at a new front clip, and from what I've gathered, it sounds like the Nova II (66-67) front subframe has the narrowest track width of 56.8", while the 67-69 Camaro and 68-72 Nova have a track width of 59.1". My 76 Camaro clip has a track width of 61.3", so either clip would be a big improvement (yay for 8" wide wheels!).

I have two questions: can someone point me to some RELIABLE sites with track width measurements for GM clips? I've done some searching and come up with conflicting results. Also, any other subframe suggestions?

ANY help is greatly appreciated!

Thanks,

Ryan
