[Vwdiesel] Alternator Belt

[mikitka]

Hey everyone.  The alternator belt on my 91 Eco diesel jetta went out. It
flew off the car so I do not have a belt on hand to measure and I can't find
my notes from where I replaced it in the past. I'm finding two part numbers
for my jetta, Autohause is showing a 10 x695 from Contitech and then there
is the other size 10 x 630 that is showing on what use to be
Stopshopanddrive.com now partsgeek.com.  I guess I need to order both to see
which one fits? At least they are not to expensive.

Thanks,

Nick
