Duster Help

I've referenced that chart before and it sure seems to me that it is the 7 1/4, however I was told it has an 8 3/4 with 3.73 gears. Also, I was told it was a 360. This is the only picture I was able to get from the seller of the front of the engine.

Look right there at the parting line to the block head. On the block there should be a long string of numbers stamped

I already told you this above^^

The 8 3/4 is the only Mopar rear axle that has a removable third member and not a rear cover
