***BOTH PULLEYS ARE SOLD*** 39-48 crankshaft pulleys. Both have been glass beaded. The single sheave (groove) pulley was a 39 Deluxe to '41 that I had my machine shop turn on a lathe to resemble a '39 Standard. They also installed the sleeve to run a neoprene timing cover seal. This was only on my car a couple hundred miles until the block cracked in the pan rail. The two sheave pulley is a 39-41 Truck pulley #81T-6312. The seal area is in good condition. $65.
