Thanks!!
How do I get ahold of him/them?



Alas, for the power steering folks like 99% of the world is, this uses a remote mount reservoir:

Problem: No alternator on my LSx motor.
Have: Alternator from my BBC and the bracket that went with it.
Solution: Adapt my junk to run with the truck pulley, waterpump and tensioner.
Here's a reference picture of the head

Basic location and spacing I had in mind.


After making some measurements (including the difference in the depth of my alternator and the waterpump pulley), I found I needed a 1-1/4" plate and I would have to pick-up a hole on the cylinder head with the spacer plate.

Got this big hunk-o-aluminum from Midwest Steel Supply. It's 1-1/4" thick, 6"x8" T6 aluminum and with shipping was surprisingly cheap. I could have ordered a smaller size, but I wanted extra just in case.

Sorry if these pictures are excessive, but I like them. I layed out the pattern using my existing bracket, made some reference marks for the holes (do not drill these) and marked the inside area where I want the other cylinder head hole to end up.





I managed to find a bandsaw somewhere and cut out the plate. You can hacksaw or jigsaw this, but I wouldn't recommend it.

After clamping up the BBC bracket to the spacer plate to use as a drill guide...

...I used a 'gunbarrel' drill bit and backdrilled the holes.

After measuring out and drilling the third hole, I mocked the spacer and bracket up to the head.


Used some random fasteners and a few drill bits and mocked everything up. I had a long steel spacer tube from another project that I cut down to 1-1/4" to match the spacer and used it on the tie-rod common-to the cylinder head.



Looks like everything lines up perfectly!

Now I need to counter-bore the backside of the outermost hole so I can install that bolt. It interferes with the cylinder head. Then I will de-chrome everything chrome and probably paint the alternator, bracket and spacer an aluminum color so it all looks uniform. And, I need to find a belt...
