Have seen 17's for like 65.00 each new with 3.5" backspacing.
Might be interested, is their some parts you might be looking for?
I have a set of kinda worn 37's on 15" wheels. And have another set of 37's with about 40-60% tread left, on 16" wheels.
Have 3 different tcases, have a few turbo bellhousing's, also have a clean set of aluminum 16.5" wheels for the 6lug toyotas. Have lots of driveshafts and manual hubs too.
Located just south of Bakersfield
