Ok. So unlike probably most here my talent is weak. I've been really wanting to stuff 10" wide wheels underneath my 65 and I've heard everything from "won't fit" to "pretty tight". My second choice which would alleviate this issue would be narrowing the frame and widening the wheel wells. I've read other's posts that did it but aside from the no talent thing, I don't have the tools and not much room so this is where I start giving money away:( for someone who does possess those attributes. Since the Chevelle is already a driver I was thinking instead of downing it for what would probably end up MONTHS, I could possibly get a 2nd frame, build that up and then transfer the body over to it. This would essentially cut down on my downtime. Also, I could install the rest of the parts myself as long as I didn't need much more than basic tools. So...in you guy's opinion, would it be worthwhile/smart/budget friendly to go with the second frame idea? Keep in mind that I could probably get friends to help me with the teardown but any welding, powdercoating, etc. of either frame would be done by professionals. I'm just not sure where to start as this is the foundation of the rest of the build. Also, I have a 10 bolt now and am planning to switch to 12 bolt. Ideally I'd like to find someone here in north Texas that can be trusted to do the work but if there was another way I'm all ears (eyes). To sum it up:

1. Lack the talent (welding, p-coating)
2. Really want to run 10" wide wheel in the rear
3. Would like to the suspension parts myself
4. Enjoy the idea of a professional keeping things in perfect alignment

I don't see where narrowing the frame and not the body is going to get you any wider tires to fit in the rear as the wheel house and the frame edge are at the same location. I too have a '65 and right now I've got 255's on the rear using 15x8 rallys on 5" back spacing and they do ok. At one time I had 275's in the rear~ They only rubbed the inside edge now and again in hard turns and to keep them from burning/squeeling I rubbed the inner side with some silicone lube...

I didn't mention the body because I know that's a given. The diameter would be significantly larger than your set up. I'd love to see your 65 with rally's. :thumbsup: I've always wondered what they look like on 65's.
