Here is a really neat alternator bracket. You all know there are no bolt holes in the ends of those great old heads. So you can't use them on the newer motors. Newer than what 1969? Anyway with these 2 brackets you can mount that alternator back on the motor. It has to be used with a long water pump and pulleys. Also you know that alternator 5/16 bolt hole is bad about striping out and so you just tap it to 3/8. Then the 3/8 bolt won't go thru the adjustment slot. We opened the slot just a little to let that 3/8 bolt go in there.
