NG Timing Belt Tensioner Pulley Bolt?

[Andy Thibodeau]

First off, this is my first post, been lurking for months.  I've got the
front of my car totaly pulled apart to do a timing belt/water pump R&R.  I
got the kit from Blau, and all the old parts are off.  But I noticed an odd
looking bolt holding the timing belt tensioner pulley on.  Looks really
non-Audi.  About 4 to 5mm 2.5" long with 2 washers in sequentially larger
size toward pulley, and a 10mm head.  It looks like the finish on both bolt
and washers is hot dipped galv.  Is this really the right bolt?  The Pulley
was non-Audi, but the pump was VW/Audi.  The car in question is a 1988 '90Q
build date 1/88 US spec.  Any replies appreciated.  Thanks in advance.

P.S.
    Where are all the early 90Q owners?  I would like to hear from all of
you, especially those who Auto-X as I do.
