55 gmc, camaro subframe, too f'n wide

[atotalnincompoop]

I hadn't worked on my 55 for a few years but recently decided to put it back in the garage to finish it off. A while back I had installed an 80 camaro subframe in it. As I start thinking about wheels and tires it has become obvious that there front suspension setups are a little on the wide side. I don't want to have to buy custom wheels at over $1k each.
I did a Google search today and had found limited information on using buick regal control arms on the camaro subframe to narrow the track by 2" on each side.
Does anyone here have any experience doing this?
