Speedometer cable length?

[2 Darts]

I broke the speedometer cable in the 72 Demon (LA 904). I've gotten bunches of little shards of the flex cable out of the outer tube, which is good from the debris stand point, bad from the perspective of trying to replace. I have a replacement cable, I just don't know how long it needs to be trimmed. Does anyone know how long the flexible drive portion of the speedometer cable is?

I know that NAPA sells the correct cable that does not need cut $20.00.
It comes complete so throw the entire old one away and put the new one on.

Rock auto also for about the same price in with the new out with the old.

I hate buying stuff twice. Thanks guys. I guess I'll have a spare for a while.

Went looking. Rock Auto and Napa showed only cut-to-length universal kits. So I went looking for a part number to cross for a specific fit.

Eureka! The magic answer is 63" for an A-body with a 904 and no Auto Pilot. After 4/7/72 it was shortened to 62". Even Mopar sold a universal kit of 80" trim to fit. Source: 1972 Mopar Parts Manual.
