Most of the delete kits are setup to use the std belt. If you need shorter ,take old belt off ,run a piece of string around pulleys , measure required length .
This will be MAX length with no load on the tensioner so you will want shorter belt than actual measurement ( unless you get someone to position tensioner while you measure)
Go to auto shop and ask for 6 rib belt X inches long

I made my own delete pieces, then used a local, small auto parts store to swap belts until I found the right length. I like supporting the local, a car guy who has a store of knowledge to assist me. My PN would not do you any good, though.

I trust that you understand the markings on the tensioner that tell you when the length is right.

I am going to put underdrive pulleys on this spring, where should markings be on the tension pulley? Anybody have an illustration on where the proper tension should be on the tension pulley.

Depends on the tensioner style.
My '87 has 2 marks that line up ; my '90 has only has marks showing the acceptable travel range so you would measure closest to the shorter end to allow for belt stretch

On two separate occasions, I have gone into an auto parts store, and asked this very same question, and they still ask make, model, year. I have to explain to them that their computer isn't going to give the answer and they have to key it in directly. Most times now, I go online, find the part ahead of time and just take the part number in with me.

I cannot recommend this, from experience with a Suburban. The power increase was minimal, at best, and the power steering effort increase at low RPM (like when parking) was unacceptable.

Just ot be clear, in addition to the excellent other comment, the markings are on the tensioner housing, NOT on the pulley itself.

The chain parts stores rarely employ anyone who knows squat about cars. That's why I prefer to go to Bob, at the small local shop. He actually has good information in his noggin and uses the computer as a reference TOOL, not as his brain. I buy there b/c I want him to be around when I get off the main path, even if it costs a bit more.
