I dont know how your stem mount for the alternator has held up, but I tried the same thing with my '70 Boss 302. Long Grade 8 bolt with a spacer cut to hold it out into the belt plane with the adjuster underneath. Halfway thru a lap the bolt snapped at the block, the alt still wrapped around the belt tried to rip the adjuster bracket off and finally bounced out the bottom just low enough to catch the road. Then I ran over it with the oil pan. What a racket! Fab a new 'Z' type or whatever to help take that load of the bolt. the adjuster now matter how hard you tighten it, doesnt do much for ya.

My solution to this was to install a bank of fused relays in the engine bay picking up power from the battery feed side of the starter relay, the alternator charge wire also connects here. Keeps everything fairly accessible, which is probably a good thing for a race car. |

I hope your socket spacers are Snap-On - otherwise people will think you are cheap. ;-)

With that much amperage you will want to consider running power to a new fuse panel to run the hi current draw accesories. I am running the same style 10si (100 amp) internal regulated. I ran a #6 wire to the relay and then to a Painless wiring junction block which feeds the 10 circuit underdash Painless fuse block and also the factory feed to the original fuse panel. The junction block makes it nice as I ran out of room on the relay post as you can see as the Robb MC starter feed needs to be on the hot side of the relay |

Never mind the sockets, you should try finding a 7" long x 7/16" UNC bolt on a public holiday.

Ha! sockets make great spacers, plus they are chromed to match.
Looks nice and clean, like new even. |

Just to close this out, got the alternator mounted up today:
Ha ha, only kidding that was just a quick mock up to work out what I needed, this is the finished job: |

Pretty sure the one I ordered is an updated version in the 10SI case and will do one or three wire hookup as needed. With the electric water pump, I won't be able to run the Motorola brackets, so will have to make something up anyway.

A Delco cs130 from an 89 Pontiac Safari is an easy install. By cutting an inch off the back of the pivot base it will mount the same as the Motorola.
