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.

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

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.  ;-)

Looks like it is a chrome Aeroflow brand  a GM/Delco 120 Amp unit then, pretty much the cheapest thing available on Aussie eBay without getting into used parts. Should get the job done.

The only other thing i want to do is to hook up a relay to the ignition terminal on the starter solenoid to turn off the thermo-fans while the engine is cranking to save a bit of juice.

Oh, and upgrade to a mini-starter.

Ah, that I understand... ended up using a head stud for my custom setup.

Ha! sockets make great spacers, plus they are chromed to match.

Looks nice and clean, like new even.

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.
