i don't think thats 4 d4, more like 10, 15,20,28, 22, just guessing here. check out casting numbers to cross reference parts book, best to find out casting number on the paper pulley hub. good luck.
I saw the D4 that it came off of and the owner can verify it.

I don't think it fits a D4 either. Some casting mumbers would be helpfull.. Jon

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
