Bare 15X7 rallye wheel singles appear to fall in the $150 range.
Personally I would not cut up a real 15x7 rallye to make something else out of it.
Neil,
Let me know how many 390 singles you have and I'll come get them all.

Only have one bare 15x7 wheel (Nov 1969 iirc) just kicking around in my storage shed. I switched over to the 15x6.5's instead as they look close enough and were cheaper and easier to get.
From what I can tell watching them on Ebay a complete numbers matching set will go for way more than what individual wheels pull down. People don't want to take 6 months to track down wheels one at a time I guess.
Even though the rallyes are more common whacking one up to make a lesser appealing yet more valuable 450 wheel seems wrong to me.
