Does anybody know of a reputable shop/company that makes custom shift cables? I have a guy at work who is putting a 5.7 hemi with a 45rfe 5sp. auto into a '74 Challenger and we are having a tough time coming up with a cable that will work. It has to be between 48" and 52". Everything that I've found in our parts catalogs are either too short or way too long. If anybody has any ideas I'd appreciate it.
