Hello -

Planning to start the A833 OD conversion in the next few days, and right now, I'm trying to figure out the speedometer cable.

The A833 is from a '77 Volare, so it's mounted into the transmission with a plastic piece that allows adjustment for different size speedometer gears (see pic). The transmission end of the cable is held in the plastic piece with a clip. Remove the clip and the cable, and there's a long cylindrical piece about 2 5/8 long (see pic).

I can easily find a speedometer cable for a '77 Volare that has the correct type end on both sides - transmission end has the long cylindrical piece, and the speedometer end has a 5/8" screw on sleeve.

The main issue is that the Volare cable is 81" long, and the original cable is about 56" long.

Does anyone know if there's a cable that will give me the correct ends that's somewhat shorter? Or, is there a way to shorten the speedometer cable (doubt it, but I thought I'd ask).

Thanks...

Chris

You need the '66-early '68 A-body speedo cable, the adaptor from a '66-76 Mopar, and the correct gear to match your rear end ratio and tire size.

I'm aware that the cables changes in '67, but what type of adapter do I need?

I'll get in touch w/Brewers regarding the gear.

The cable changed in early '68 models....went from screw-on speedo end to a clip-on. The adaptor is a separate housing for the speedo gear. The speedo cable threads onto this adaptor.
 
What you need:
Speedometer cable, '66-'67 A body; 63" long, has 5/8 and 3/8 screw-on fittings on either end. The 3/8 one fits your speedometer, the 5/8 goes to the transmission speedometer drive adapter.
More Information for PIONEER CA3002

Speedometer adapter; '66 and up, all transmissions use the same adapter.
Post a wanted ad or contact Brewer's.

Speedometer drive gear; '66 and up, all transmissions, tooth count dependent upon your rear end gearing and tire size. Again, post a wanted ad or contact Brewer's.

The adapter you have is a later model single piece with the cable- yours just became separated from the cable and is not useable for your application.

Just in case someone is parts hunting through auto wrecking yards....that adapter and speedo gear are not the same for all '66-76 models 100%. Probably closer to 95%. Many truck and van manual transmissions, and 4X4's use a different setup. 4X2 automatics, yes.....same as the cars.

And there's a special adapter for 26 tooth and greater gears, normally found in trucks and vans with steeper gears, and one for 25 tooth gears and under. My point was the same adapter was used in 3 & 4 speed manuals, and 904 and 727 automatics; just to make his search a bit broader. I should have been more specific, but we don't know his rear gears or tire size.

I’ll be following this thread, as I have a back-burner project ’66 Dart 170 I plan on doing this to. I suspect I’ll have an easier time with it since the ’66 cars lack the ball-and-trunnion.
