just some more pics sorry about the size. I used a steel procharger bracket not the aluminum from ATI. Im going to look for a small spacer so I can reduce the amount of washers under the pulley but pulley spins freely

oh ok, now i see what you did.. In the last post, this picture made it look as if the hole was all the way thru the bracket. Your latest closeups of the hole show that it is not bored all the way thru. I still cant figure out why that first pic of the hole looks different from the rest of the pics you posted just now.

You should be ok with that, just as long as you account for the extra spacing away from the engine where it bolts on.

Actually not my idea, Machinist wanted to do that instead of cut two levels into standoff. I dont think I would do this to my Aluminum bracket only the steel version.

That second step in the standoff was not designed to fit into the J-bracket, so his statement of doing that *instead* of cutting 2 steps in the standoff does not make sense at all. I dont think your machinist understood that the second step was just to accommodate a standard off the shelf at Lowes washer (see this post). But hey, there are several ways to skin this cat.. As long as the extra pulley is there, you will benefit from extra belt wrap and decreased belt slip.

He was going to find a regular washer and modify to correct size but he had some other type of washer as seen in the pic, i'm guessing he used whatever he had laying around, plus he didnt charge me. I used the factory idler pulley but I think I should have bought another 8-rib procharger idler. The factory idler is about half the size of procharger idler.

Welp, you can always get the procharger 8 rib idler at any time. It has the same ID as the stock pulley, so your standoff will work with either.

Ok guys, If we do a production run of 20 of each of the two lengths 2.5" and 2.75", we can get them to you for 29.50 each.

These would be made out of steel. I don't like the idea of threads pulling out of the aluminum standoffs.

These are built to the specs that ChevyChad posted on the first page. What you see is what you get.

I would have to have a guaranteed 10 orders up front prepaid.

I'm in for 1 in the 2.75 length. Steel would be better. I'm willing to be their will be less bracket flex with steel.

Good idea. The price is not bad either. Maybe you could start another thread so people dont have to dig 11 pages deep in this one to find this info
