I bought a 94 TA that has an underdrive pulley and overdrive alternator. When i got the car it had no belt.

What belt do i need?

I tried the dayco 5060590 and it is too long. I can't find a shorter belt at the autoparts store.

HELP!

You tried a 59" belt and it's too large? The stock length is 64.25". That's a good drop...how much too large do you think it is? Remember to take into account the tensioner when guessing the length.

Why not measure just to make sure?

I bet its an early model 94 or a diffrent ac compressor. Run a gates 5060577 belt. I used to run a 93 compressor to shave some belt length. 93 model ac compressors had 2 in smaller pulleys.

Interesting to know,I'll add that bit of info to my ever expanding "Differences in 93 LT1s" mental data base haha But the smaller AC compressor won't gain you any power unless you run the thing ALL the time. Those compressor clutch pulleys spin so effortlessly it's amazing. I've heard them still spinning minutes after a blown belt.

Anyways, there should have been a pamphlet, or at least a small piece of paper, with the UD pulleys that tells you what belt to run. I'd figure the manufact's website would have an online manual if they didn't include anything.

You running a relocated alternator or no AC w/o the AC Delete pulley? Because I've not came across a GM Serp Belt setup that runs that short of a belt that runs all the accessories. Not saying there isn't one, just saying that in all my dealings I haven't seen on. I know that the GEN III/IV motors use multiple serp belts in some vehicles though.

Keep me posted if it works.
