okay, i'm not trying to be a dumbass here, but i want to make sure before i start taking things apart. here's what i'm doing.

i have a 1973 schwinn collegiate (5 speed) that i've stripped down (removed all brakes, deurailers, cables, etc...).

i also have a late 80s schwinn cruiser (single speed coaster).

i would like to place the wheels and braking set up from the cruiser onto the collegiate.

is there a component in the bb of the cruiser that assists the coaster brake, or is it just the little piece that attaches to the frame by the rear wheel?

does this make sense?
