Trying to put it back the way it was suppose to be but I can't find a belt to fit....I may just leave it off at this point.

That's the belt I'm using on my 69. Have you changed a pulley or anything? You could take that belt and get one that is slightly longer too. No idler, belt in the rearmost groove on both the crank and the water pump. I know of one guy that left that belt off and every time he jumped on the go pedal the belts started squealing.
AIM for the 69 belt routing:

Thanks Tim, That aim pic does not have my routing diagram. The belt is too loose.

With no adjuster, you just have to trial and error one just a little shorter.

If it's too tight, it will eat the water pump bearings. (Don't ask!) Keep some play in it.

Read THIS thread, especially the reply by John Hinckley (JohnZ). You'll need to go out and buy one of those two belts (or both and return the one that doesn't fit).

The 68 AIM has a similar page and lists the old, original GM part numbers for the belts. Using the original part number, you might be able to scare up a correct replacement belt.

installing that belt without the use of two threaded rod studs is almost impossible.

cut two short threaded rods and screw them into the water pump..slip the belt over the crank pulley and the water pump pulley and slide the pulley over the two rods, insert the other two bolts, remove the threaded rods, insert the other two bolts and you're done...

GDINA is spot on in regards of how install that first belt it is tight have patience if it helps I used a gates belt 13A0825 /9325 on the first one it has been on for 2 years with out any problems.
