My son and i are swapping a 289 into a 6 cylinder 68 coupe. We don't really have a frame of reference on how the alt bracket is mounted. Could anyone post a pic on where the bolts go and if possible give a idea what bolts sizes are required?
I don't know if this helps, but here is my '66 289 alt. bracket. My bracket is mounted to the passenger side head with a 7/16-14 bolt. The other 3 bolts are from the water pump. The top water pump bolt requires a spacer. I don't know how other style brackets work.
