Speedometer cables part numbers

Knowing the year of your car & the type may help...... ;-)
1976 dart sport was a slant six car but now has a 73 360 with the matching 727 tranny the original one out of the car was the right size 7/8 at the tranny and push on at the speedometer but the cable was broke inside the cable housing. 68-76 these years are all supossed to be the same I found a Mopar part # 4897646AA for all A,B and E body cars. So push on one end 7/8 on the other. I'm looking for inexpensive replacement brands and part numbers. I want to try one of those first. And if anybody has issues because they have a junkyard tranny in there car they will have some reference as to cable end size, screw on or push on at the speedometer and 7/8 or 5/8 at transmission. When you go on Amazon or try to look it up on auto parts stores they don't say the cable end size. So if anybody has went through this hassle. And it's hard to tell so put a brand part #, length, what ends and where you got it.
