Belt gut check please

[Gippster]

Installed a new alternator, followed the recommendations I found in the forum about the belt, but would love a gut check, make sure I got it.

seems to be the wrong belt,
too long, out of adjustment on alt?
too narrow, sits too low in the pulley of the alt and the PS pump

did you measure old belt against the new belt?

It’s what the shop supplied back in the day, but I have OEM belt in storage, will try swapping.

Proper Belt Top width needs to be a 17mm or 0.625"

OEM belt should still be available from Toyota. The skinny belt that's slightly longer is typically used when folks convert to the Saginaw steering pump. It works fine nestled into the wider crank and alternator pulleys, but has to be a smidge tighter so it doesn't slip. For your purposes just head to the dealership and grab the stock one. Might be good to have an idea of the part number on hand when you go, sometimes the parts counter folks aren't adept at finding parts for these old trucks. Consult the Toyota EPC for part number.
