andereck...one question...my original pullies had a lip on each side...the ones I ordered in the past as replacements did not...the ones you sent recently have the lips again...is there a reason why there are some w/ and some w/o?
just curious...

 

As long as everything lines up as it should the two designs are functionally equivelant and either can be used as long as there is room for the flanges.

 

oh...I never had issues w/ or w/o...just curious...
