For usable stock take-offs from wrecks, contact the U.S Pantera vendors- Larry Stocks PPC Carson City NV, Panteras by Wilkinson in SoCal or others that buy wrecks. For stainless steel repro's, contact Hall Pantera in So-Cal. Note- stock tanks made after late 1972 for L models were chrome plated inside & out, then painted black. That usually took care of rusting even for owners that ran straight water without anti-freeze. Of course, it HAS been nearly 50 years....
