I know I'm looking for the 24v (27si alternater) but does someone have the acdelco part number for the correct one I need want to order it but not sure of the AC delco number. Thanks Bill

321-668 will get you a 65 amp 27si alternator

I had a local alternator shop build me one for $150.00. I used another deuce alt bracket and a spacer to mount it.
