If the pins measure app. 7" and not 5.5?(specs on TSM) then they are correct. Look exactly like the ones I pulled off of a 78 eldo. You will have to fab a cable bracket on axle tub,something I have not accomplished 'cause I dont have it mounted under truck or rebuilt calipers. Plan on factoring in $57 and up for exchanged rebuilts. My small parts were crumbled upon disassembly.
Some people are saying that this lever style is the inferior of the two, but I found some just like this and didnt want to have to buy two later calipers for brackets and these/or cough up core
