Denny-

It is funny you posted your message because I just got the same tool in the mail yesterday. The "funnels" don't seem to be of much use for our rear seal because the shape of the seal groove is more of a rectangle, whereas the two funnels are cicular in shape.

I'm not sure, but I took the two aluminum extensions to be the neoprene seal "punches". I guess you could use those (esp. the small slightly curved one) to help push out the old seal. They don't seem of much use to me, though.

As for the steel strip, the only thought I had was a cutting guard, so you could protect the crank journal when you cut the seal in place. The Best Gasket brand seal I have came with half a toungue depressor for that purpose, so this is the only use that makes sense to me.

I'd be interested to see what kinds of applications would actually use the funnels.
