BRLCLA Thanks for the offer and the link. If you get a chance send me a few pics of the mounts I may take you up on that offer. I was looking at the Dorman AC delete pulleys and was considering doing something similar. I found a few that looked like they could be made to work with a little effort.

I also looked at rotating the tensioner clockwise about 150 degrees. That could be done but would have required grinding some clearance off the housing where it was closest to the harmonic balancer and drilling one dowel hole in the boss that the tensioner mounts to.

However, the simplest option was to pick up some 125mm bolts and double nut them to use the alternator as a tensioner.

Closeup of the alternator. Probably use some blue locktight.

Belt I used for this setup. Compliments of a sweet lady at Advanced Auto that let me behind the counter to rummage thru all the belts :D

Need to pick up some proper exhaust stud bolts. They are 10x1.5 and alternator bolts were 8x1.25

Worked yesterday on some mounting ideas. One on each side of the engine and one on the front. Also stated on the new stand so that I will have access to the bell housing for measuring and planning for the reduction adapter.

The motor mounts will ultimately be made out of 1/4" stainless plate.

the stand will get some x bracing as well.

You go it going right... you dont need the front mounts I have... I bought them just for pattern purposes on building the mounts you already have built. Good luck to you. I hope you give Jerry @ BNR a shout to tune it when you area ready. When you get down to wiring and needing to replicate the VSS signal drop me a message on FB. Happy to come help out, but I leave the fabrication work to the more experienced welders. Im just an engineer and can read books and weld copper wires :-) lol
