Alt bracket renforcment 4 A/C Air pump delete
I know quite a few people on here have done the A/C and air pump delete, and I know some people have had problems with the bracket and/or alt case breaking, to hopefully provide a little insurance against this I did some extra fab work. I made some spacers out of aluminum rod drilled and tapped them and fitted them in the alt bracket drilled 4 holes in the bracket made some custom washers and bolted it all together, this should add some structural rigidness to the bracket. With the Hooker 2151's and this setup I also had to fab my on rear alt support which I did this out of 1/2" steel rod.

That looks fantastic. I am currently fabbing a rear brace as well. I left it off on my last build and I went through 3 alts. What alt are you running? It seems as though they fly apart on the inside if I go over 6500 rpms

If you don't mind, can you tell me where you got those insulators for the plug wires?
Also, I recently put LTs on my '96. It had 2 braces on the back of the Alt. I left the most vertical one off. It went to the back bolt on #1 exhaust tube. Do you think this will cause a problem down the road?
That bracket is sweet!

That looks good, although I never had an issue with the p.steering /alt. bracket I think the back alt. brace is what helped mine. I remember when I did the build the first time around many here said they were breaking alternator cases. I made a rear support then and fortunately I have had no alternater case failures over the last 4years.
If I can ever find a true bolt in manual rack that OEM bracket will be gone (along w/power steering), and I will make a dedicated alt. bracket.

Alt is just an AC Delco oem replacement. The rear brace actually wasn't too difficult. I used 1/2" steel rod I picked up at the hardware store. I was amazed that with just a normal propane style torch head you get almost anywhere and using it with MAP gas I was able to get the steel rod hot enough to not only make the necessary bends, but hot enough to flatten the ends out. Then using a grinder I slotted the ends to go over the bolt/studs.

I haven't heard problems with the Alt or brackets on the LTx engines, but if your worried I'd say fab up a bracket shouldn't be too difficult.
Thanks for the compliment.

What I really thought about doing that would balance out the look of the engine compartment, plus move some weight to the pass side of the car is relocate the alt to the pass side with an adjustable mount for setting tension, return to reverse rotation WP and switch to standard rotation P/S pump, but sounds like more work, more parts (therefore more money) and most importantly what I've got right now works.

No it won't hurt anything, and I 'm sure it will add strength.
Manual steering would be harder to turn, but every hot rod I had in the past had manual. To me parking was the only byatch.....this just gives me another reason to keep skiinies on the front all the time.
Speaking of moving things, and if I keep the P.S., I would really like to do this, unfortunately it will have to wait:

I think as Mseven said though most important when going to the turnbuckle adjustment for the alternator is making sure you have a rear brace on the alternator.

If you did not have the rear support, at that point the only thing offering any real support would be the power steering/alt. bracket. Which in part is why I believe Ultraviolet 70 decided to add some bracing. That bracket is only a cast part and it carries more load due to p.steering and alt. It basically creates strength through it's design (triangular), width, and it's connecting points which ties everything directly to the block. The additonal support from rear of the alt. ties it to the block in another loaction and helps the alt. from flexing towards the rear of the car.

I think that is possible too, (as you mentioned w/reverse rotation pump) when I was looking at this I found nothing readily available. My conclusion was I would have to make all the brackets. to make it work. Then I saw that package in the GMP book, said that's it.........then I saw the price.$$$$$
