I'm trying to get some new belts for my SD here and well, I'm not sure if I need a 1000 or 1037 length alt belts.

I have a single 1000 on there and it's VERY tight, took me a good deal of effort to just get that off with the alt tensioner relaxed (volt regulator took a dump so I had it tested if you must know. )

Any clues as to which length I'd need to run?
