James,

I want to do the same thing. Buy new wheels. I looked at the site.and I would guess you buy a 15x6 with a 6-51/2 which would give a 33/4" rear spacing. I would also imagine that you could buy a 15x7 which would give a 4" rear spacing. I have got some information from www.steelwheels.com and they indicated a 6-51/2 pattern and this had a O" offset. What size did you buy?

Thanks
Al in Seattle..
