It is going to be a 4300 series cable, could be a 4300CC or a 4300BC, B denotes a bulkhead end and the C denotes clamp
So if it has a threaded trunnion on one end, it will be a BC, if it has the funky grooved clamps on both ends it is a C
As for the length, measure from clamp to clamp, it is normally stamped into the jacket somewhere.
