Vintage wheel works is currently working on reproducing the American Torque Thrust wheel
from the 60's. It will be 15X7 with the same off-set offered during that period. Vintage claims it will be approx. 6 months before it is offerd. They will update their web site as it progresses
www.vintagewheelworks.com.
Phone number is 562-906-8600. Cost will be approx. $800.00 for the set. This may be a good alternative to finding an original set.
