Otto, if Dave's pulley doesn't pan out I should have one too. No aluminum compressor brackets though, the ones I have are steel.

Based on ~630 mile round trip to San Antonio last weekend, these old bones don't take too well to long, non-A/C drives in the summer heat down here anymore. A/C is on front burner, as I'll likely take '69 Kadett to OMC . . . if I go. Now you know . . . any of those in anyone's stash somewhere? I'll document and post on one or both projects.

One of the ultimatums I had made to myself concerning the drive out to the OMC this year was I would only go if my wagon had A/C (my Canadian blood doesn't tolerate heat and especially humidity). That's a moot point now since I don't have the money to go and the wagon is nowhere near completed anyway. But, I was going to use the A/C I stripped from my Nissan Sentra which has a nice, efficient, lightweight compressor that will easily fit the turbo wagon. That said, I was going to have to make a mounting bracket for it anyway.

Otto, if you have a detailed drawing I could probably fab up an aluminum bracket in a couple of hours for you. Just a thought, and the practice wouldn't hurt me

Sounds very intriguing, Bob, thanks for the offer. I'm enclosing a picture of the compressor with all the pertinent mounting dimensions so, if you can do the mockup of the block and crank with twin pulley for bracket dimensions there, all should be good to go. Let me know if you have any questions about compressor pic. Thanks for entertaining this.

How would you want it configured, as far as the 'clocking' of the compressor? I can see the bolt (size?) for the belt adjustment at the top of the pic...where would that be situated (since I don't know the routing of the compressor lines it would be important). What diameters are the lower mounting tab holes?

Still'd like to know c/l of front dual drive pulley to block face dimension if you have time.

I have a couple blocks sitting on an engine stand waiting for a pulley to measure from, but the double A/C pulleys I have are in my storage trailer, which is not local to me. If I can swing by there this weekend I'll try to get one. This weekend happens to be a non-automotive weekend, just trying to clean up some messes I started!

Had to rethink the whole thing a bit, as I said, but if the offer is still good, here's a drawing of the driver side compressor bracket. Not drawn to scale (couldn't find a "grid" in Paint!), but all the dimensions listed are accurate. The 2.675" dimension between the back sides of the pivot arms is the most critical as pump arms will mount to it from the rear. Mocked pump up to run off front pulley on driver's side and will have to fab passenger side alternator bracket as well. Up for that one too?

Looks simple enough, and I happen to have some 3/8" thick 6061 aluminum laying around too. Let me know what the second bracket will be, it's easier to make 'em both at the same time.

Would you, or anyone else reading this, have an extra 1.9 aluminum alternator bracket and an unmodified stock 7-blade WP fan?

Otto, don't forget there are at least three different types of aluminum alternator brackets (plus the older cast iron brackets) There's the 'thin' style that is very prone to cracking, then there are the thicker-section pieces, and of those there are two offsets (away from the side of the block, not fore-aft). This fact used to really mess me up swapping stuff out when I'd try a fan belt and it wouldn't fit because of a longer bracket!
