Picked up a DDS or DDS type power pulley last weekend.  It measures:

a.  135mm or 5.3" overall diameter.  What size fan belt is used for this pulley?

b.  44mm or 1.7" diameter sand seal surface.  Is there a modern press in sand seal that can be used for it?

Go to your local Ford dealer and buy a JB332 fan belt.  The OEM to Ford is Gates.  This belt is indestructable!
It is 7/16" wide, 33¼" long.  Your pulley ratio will be slightly above 1:1.

Thanks Bruce. What do you use for sand seal?  Or do you have a non sand seal version.

I have a few of those pullies, and all of them are VW style that screw the oil back in.  I've never had a leak.
