About to start rear end swap... a few questions?

ok from experience and readiong ALOT the backing plates are a swap over, the drums wont because its small bolt pattern but you can get them redrilled, the e brake cables are fine, you dont have too grease the green bearings they are a sealed bearing you dont have to lube up the third member.. which car is this if its a 108 wb dart demon duster the driveshaft should be 49 in from center of you joint to center of you joint whith a 904 trans, a 727 trans is alot longer so the driveshasft is alot shorter, the shock moutn plates from your 8 1/4 will work and the u bolts but you can get new u bolts at autozone, as long as the u bolts from you old rear end are 3 in diemeter they will work i think they are... is this a sure grip reasr if so you need friction additives mixed in with the gear oil oyu use, you should only need about 2-2 1/2 quarts of the gear oil fill it from the drain plug until it starts leaking out and you topped offthats it.......
