I installed a rear disc conversion that uses the GM calipers but am having a hard time finding emergency brake cables that will work with the calipers. The kit I got did not come with the cables. Any insight on where to get them? Part numbers? I talked to Inline tube and they will make me a set to my specs but they also want big ****$ for the process. They said they dont have any pre-made ones for the year that I have. Its a 1978 Nova with a 10 bolt and TH-400 and ZZ454 engine. I know they make the kits with the cables for the 3rd gens but I think the setup is different than that on the 4th gens. Thanks in advance.
