OK, so let me just say that having three trucks things get a little confusing sometimes and I forget what goes with what and how. An '01 LS swapped '74, a 71 cab on a '69 chassis, and than this 99 Vortec engine in a second gen '78 Camaro subframe on this '54, so cut me some slack ha ha

so now that it is all coming back to me, I realize that non of the three alternator mounting bracket sets that I have will work, because they are all for the long water pump (one of the three shown below)

I think sometimes in the 70s GM decided to switch from mounting the alternator on the driver side to the passenger side, and the general rule of thumb is and I may be totally wrong, keep in mind I am only talking about the small block here, also they decided to mount the alternator bracket to the long water pump, I HATE THAT, I hate it when one component hangs off of and needs to depend on another one, WHY?

short water pump = alternator on driver side

long water pump = alternator on passenger side
