One thing always leads to another. (Pulley Help)

Some of you may recall my earlier post on Flexplate and matching Balancer for a 1990 302 in a 66 Mustang.

I had a 28 Oz instead of the correct 50 Oz. Now that I have the correct 50 Oz. flexpplate and matching Balancer my orginal pulley no longer fits. I'm not in the mood to upgrade all my pulleys, I only want to purchase a crank pulley single grove only needed to meet up with my orginal alternator and water pump.

Can anyone help with part numbers?

Thanks in advance.?

Interesting problem. Is the problem the 3 bolt /4 bolt mount on the balancer or is the 50oz balancer a different thickness than the 28oz that you took off? Which would affect the depth of the crank pully.

Mustangs plus has this also:

This balancer features 289, 302, or 351W sets of timing marks, accepts all 3 bolt and 4 bolt crankshaft pulleys, and is made of nodular steel. Buy one for a 5.0L engine now and if needed on the 289, simply take it off the 5.0L, buy the other counterweight, bolt it in, and install it on the 289!
