Mopar Rally Wheels Question

Im having trouble finding a dealer that sells the Mopar Rallye Wheels - 41 Series (they came on my 71 Duster 340, but i upgraded to a 4.5" bolt pattern in the rear, and i would like to find 2 of the same wheels (with the bigger bolt pattern) to match the fronts...instead of having to buy new wheels and tires all around)...ive been told I could find them aftermarket, but i havent been able to find them..

If anybody knows a company that makes them, please let me know...thanks

I think Stockton wheels sells them, check their website.
