I bought these chopped frames as a hedge in case the ones I was having chopped got ruined. The chrome was chemically stripped from them and the diecast welding was neatly done. If you know how hard it is to find someone who can SUCCESSFULLY, weld diecast, you will appreciate these already being done. You can chop to suit your car or use them to chop down to. Measurements shown are quite accurate. They fit the Chevy and Pontiac Hardtops only, maybe Olds and Buick but I don't know that for sure. Paypal
