71 Duster 360 (new project)

Decided to tear apart the 904 that came out of the Green Duster...I was pretty sure it had fried the rear clutch pac...lol

Welded was more like it....but more to it....i took the pan off yesterday and there a nut in the pan.....ok...where did that come from...so I remove the valve body...and the rooster comb and gear selector stays in the trans as i remove the valve body...the nut cam off the bottom of the gear selector...and detent ball is nowhere to be found either.....
I remove the tailshaft....and i grab the output shaft and it comes out.....all the internals are still in the trans...Lol...the snap ring that holds it all together is not there...

I get the pump out....that looks ok....i grap the input shaft and out comes the two clutch packs with the front planetaires stuck to it...finally find the snap ring...and get the pllanteraires off the rear clutch pac off .......the rear piston just slides on and off the rear drum....gee maybe that is the problem....oh well....

make up a parts list and see what i got and what i need to order to get this back together...
