Can anybody help me finding out how Many splines The output has on a 903 transmission.

I have ordered a 26/30 spline a833 od and I’m worried that it won’t fit with the 30 splines output.

I’m quit new in this area so any help or advise will be much appreciated.

My car is a 65 dart 170 slant six 3 speed 903.


Thank you

I could be wrong ,and I'm sure of the KIA's (know it alls) will chime in.I thought 65 and earlier all had trunion pin driveshafts that bolted on to a flange on the transmission. Starting in 1966, slip yokes were used.
 
And . . . as far as Overdrive four speeds,there were two different output spline counts.

thanks. if it ends up being wrong with the 30 spline output, am i wrong or is it possible to change the output to a 26 spline output :)
 
The simplest solution is to change the yoke on the driveshaft, to match the trans.
AFAIK there never was a small shaft short A833 direct fourth trans made.
But there were with the overdrives.
I suppose the overdrive M/S could be adapted to work with the regular A833 by fabricating a third-gear bushing; but the 3-4 synchronizer would also have to be used. Not sure if those parts will play nice together, I've never looked.
But it's a bit of a pita to swap mainshafts.
Much easier to just swap yokes. 10 minutes with a big hammer and yur done.
OOps I missed that you ordered an A833od

In this case , the ratios are very similar to the A903, but with the addition of the .73 overdrive.
I'm guessing you are also contemplating a rear gear swap. For the 170, that sounds good; cuz not sure she could pull 2.76s at 65=1800rpm IDK. Meh, that's only ~130 ftlbs required so maybe.

Have you swapped over to the 4 spd OD yet?
