73 Duster Twister Guy

OLD BOLT AND KNUCKLE BUSTER, NEWBIE HERE. Been wrenching since 1963. Built a **** load of SB Chevys and Fords for buddies in my high school days. I was so car crazy the parents wouldn't let me get a car, but I could get a motorcycle LOL! Still riding Super Bikes at 71...must have some loose bolts upstairs! Bought a new 1968 Roadrunner 383 4 speed when I was in the Army, followed by a 1970 Duster 340 4 speed car....of course I wish I still had them !!! Did a resto 70 Duster 4 speed 25 years ago, but divorce forced sale. Last 25 years I got into Super Bikes, but recently bought and all original(paint & interior) 1973 Duster Twister Cali car, 318 3 speed. Just picked up a 1968 NP A833, A body 4 speed trans. Will be looking for a 71-72 360 to build as a 408 soon. Will be saving and preserving the 318/3spd. Grew up on 8.75 rear ends & not familiar with the 8.25 for strength or durability.
*** I researched the 73' Twister before getting it but found zip on Production Numbers, so help with this would be appreciated ! ***
Just call me Ted
