318 aftermarket balancer, 9/16" thicker?

my new off brand damper

http://cgi.ebay.com/ebaymotors/ws/eB...name=STRK%3AME WN%3AIT&viewitem=&item=260208386861&rd=1

is 9/16 thicker than the stock damper. i was able to find a crank pulley at the junkyard that is ~9-16 shorter, a 3 belt off a 73-74 small block.
So I went from this

to this


now, the new crank pulley is a larger diameter and interferes with the water pump pulley! I have this feeling that getting the water pump pulley from the same motor would get the offset all wrong on the water pump. (mine is a '76 with just power steering)
now I dont know where to start. Suggestions?

The best place to re-start is to return the wrong balancer and find the correct one. By the time you fix the water pump problem, then the P/S problem, then comes the alternator and A/C of you have it. Sounds like you just got the wrong one, and chasing down the "correct parts", if you can find them, will take a lot longer than starting over will.

I think you're right

I called Raceparts, the ebay store I bought it from, and spoke with John. real nice guy, knows his stuff, and said knowbody else has had a problem, but to send it back for a refund.

Contact Damper Doctor. They can rebuild your original damper with new elastomeric material or they may have a rebuilt damper in stock.

I have delt with that seller too, been very pleased. It's good he's going to refund your money.

Any chance you actually have a 272 crank? (i'm NOT a Mopar guy! LOL)

sure dont think so, as far as I know the motor was unmolested out of a '76 dart.

even in the pictures online, all the all metal sfi dampers look far thicker than the oem replacement ones.

Maybe a difference between the two depending on factory air and non? Just guessing.

I had that thought too, but no online supplier shows a difference.
