I was doing a search on starter cables for my mustang and found this thread which is over 1.5 years old, but found it interesting enough that I had to respond as to what my car had on it. I too bought my new cable setup from Marti a number of years ago and bought two J straps also because that is what my cable was mounted with, but now find that both are incorrect for my application, cable to short and J straps long and small hole.
I have the same cable setup as Carl has indicated and would like to post my findings also as my car is a very early Dearborn built 1970 Mach 1. The cable is around 45 to 46 inch long and has two short J straps with holes for the 1/2" plain head bolts like the grounding cable, which attach it to the block along the oil pan where the notches in the windage tray are.
I can not find an engineering number on the cable or Canada on the ends, so assume it is the one manufactured without and had a tag by the solenoid. Additionally besides the two shorter J straps the mesh insulation sheath needs to be 14" long as the Marti and Dead Nuts cables only have 9" which is to short to bolt the straps to the block using the threaded mounting holes. I have included the Marti parts in the pics for a visual comparison and the three bolts are the original bolts for the start and ground cable mounting, I just had them plated in silver zinc.
So to this end, I am not clear if Marti or some other manufacture is now building or going to build the correct cable and J straps to match what was originally on my car?
