hey all, i'm thinking of running rear disk brakes on my truck, the whole kits are like 500 bucks online, i can get the parts cheaper elsewhere but i still want to keep my E brake, what can i do to still keep it but not buy the kit? different calipers? i'm told some cadilliac ones will work with an E brake but i dunno. any ideas? one of my ideas is to use a drum E brake out of an M37 which runs off the back of the transfer, but that would take a little more work.
