Lots of wheels are 250 wheels (they are stamped with the p/n), which looks similar to the '70 wheels but the date codes will be 6 or 7 ('76-77) some sellers have even gone as far as drillling the 6th hole and changing the Goodyear tire that was on it to a BFG. The 250 spare which was used on the F bodies are a $12 wheel at the JY.
