Im going to an auction next week with wheels and caps and rings for sale,
4 wheels are 15 x 7 with K-1-7 and near air hole are these numbers 1 @ 27 FM
Anyone have a reference to this wheel code?

Also center caps are #3925805 then GW55250 there are 9 of them, is there a year of manufacture in these number?

thanks :beers:

Are you sure they arent FW code?? hat would be more likely. Then they would be the typical 1970 and up Monte Carlo Ralley wheels. The 3925805 is the ralley wheel center caps and were used 1968 and up throughout the Chevy Lineup.

pretty sure it was FW but maybe the stamper was playing games and turned the punch letters around? :) Thanks Mike
