727 vs 904?

I am rebuilding a 904 the pass couple of day....so what does this "built" 904 had in it..

stock clutch disc...stock steels..
kevlar front and rear bands..
stock sealing rings...stock thrust washers..
stock pump..


upgraded parts... 24 spring kit for the front drum...
Tranzact of Indy transbrake I bought back in 1992...

Trans came out and is gong back in a 71 Duster that has run 10.60s....

build what ever keeps your feet safe and lets you sleep at night...
