Speedometer cable question....

Brewers performance ( Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists ) does carry the correct replacement speedocables for early A's 65 and back but $130 plus shipping. Don't try Rock auto they sell you the wrong one, I did try to contact RockAuto about this but nothing in their catalog changed.

That's what I am trying to get around, but hay, it is what it is and I'll buy one if I have to. Did the later three speeds go to the larger diameter housing? I guess if you really wanted a lot of work you could change the whole tail shaft housing. I won't be going that way though. Thanks yall.
