Any Problems Using This A904 Transmission

That is a very good cruiser tranny. It likely has the wide ratios and a lock-up TC. Install everything from the donor car.But find a column thats more at home in the Duster, unless tou are planning a floor shift. Those parts will need to come from a different doner, probably a 67 to 72 A-body. Dont forget the NSS/rev lite harness. The governor may not work the best in your Duster, but for a cruiser, may be fine.Swap the speedO gears if the rear ratios are different.good luck.
