Good set of ram horns, came off of a 283 in a restored impala. I ran the numbers and the driver side is a 62 and the p***enger is a 58 according to the database i used. The p***enger side has been modified to accept a donut without the heat exchanger. P***enger side has brand new studs and hardware. Comes with new donuts and new gaskets still in the package. Also included is factory mounting bolts with the locking tabs. Price is 100 plus shipping.
