When doing transmission swaps, adding OEM mechanical cruise control, or just to get rid of the "bouncing needle" syndrome - you may need to change or replace the speedometer cable.
The following are NAPA part numbers and lengths for speedometer cables that have the 1 small, 1 large threaded collar ends (not "click-on").
BK 6151602 = 38" BK 6151603 = 50" BK 6151604 = 63" BK 6151605 = 75" BK 6151606 = 87" BK 6151607 = 100"
(The measurement is roughly from threaded collar to threaded collar)
