Guibo Size

[SwadePM]

I am ordering a new guibo for my 1989 325iS 5 speed and need to know if my guibo is a 10mm or 12mm? Anyone have an idea of how to find out or just know off their heads?

Pelican Parts lists it this way, although it does not mention a size I would think that there was only one size for your car and particular year/model/etc.

Flex Disc, 318i/is/iC (09/92-99), 318ti (1995-99), 325i/is/iC (thru 11/94)
BW-26-11-1-227-410 $39.10

10 or 12mm? I assume that means the bolts? Becuase the guibo is a rubber disc, about 6" x 1" thick. There should only be one size (as big daddy said).

BTW The only thing I can see being different is if you have an automatic or a manual.

Guibo bolts on an 86 325 ES are 17mm

AFAIK all guibo's are the same on the 3 series cars. even autos and manuals are the same. - 3x 17mm head bolts bolting output flange on gearbox to guibo. 3x 17mm head bolts bolting guibo to prop shaft input flange.

When installing make sure you install it the right way - the little arrows should point to the flange that that bolt bolts to. Clear as mud?
