what year truck is the engine in. If it is a 55-59, it prolly has that horseshoe front engine mount that straddels the front on both sides. I took the original generater mount and redrilled it so an alternater would line up with the waterpump pulley. If ths is in a 55 1st serries or earlier, the alternater bracket that Patrick sells should work great.

If you need an extra pulley, maybe a harmonic ballancer from a 302 millitary block would do.
