Need a spare.

Unless I can find a newer after market style that's aluminum. I can weld aluminum that as well. I'll feel better if there's after market available and I ruin this one.

I'll even swap this steelie for someone's aluminum.

I need the triple shivs.

If all 6 bolts line up that'd be a plus. This one only 5 actually thread into the balancer. Oddly the center hole centers nicely and square. Weird.

I have this one. Can't remember what it came off of, but it's 7 1/4 inch diameter, 3 1/8 inch deep. Pay me the shipping from Tallahassee to you and I'll let you have it.

Not weird at all. The bolt pattern changed in 1972 from one staggered bolt 1971 and earlier, to an even bolt pattern '72 and up. It applies to both pulley and balancer. You can elongate one hole on the pulley if you have a mismatch, so you can install the 6th bolt (recommended).

Whew. Glad its not weird.

You think a 6th bolt is going to make a difference going from Mopar crank keyway to this idea 3/4" shaft 3/16" key?

I think Mopar crank and key way larger diameter.

kinda. turning a pump. I'm going to send it. i'm assuming the mopar crank snout is a bit larger diameter. i've checked summit racing, and tried googling some photos, but can't find an actual measurement. I did find the part# for the key #106751, which translates to 3/16" 3/4" long.

All things equal, the 3/4" shaft with the 3/16" woodruff keys in the yokes, one of them should shear first before the key on the mopar crank.

Kinda wish i knew how much torque they'll take so i can size my pump not so greedy to avoid possible headaches.
