A-833 2.47 1st gear change to 3.09

Here's a question that might be relevant to the gear cluster swapping discussion. Do all of the ball & trunnion output A body 833's have the 3.09 first gear? If so, is it possible to swap those gears in and still retain a 30 spline slip yoke output? I've never had an 833 apart, but not afraid to try. I have a 65 Barracuda that has a warmed up 273, and I am swapping to a 4 speed. I have a fresh 833 OD, but....well, you know! :realcrazy:

I took my original A 833 ball and trunnion 3.09 1st gear transmission and converted it to slip yoke using (what I believe was) a '66 trans main shaft and tail housing. It worked. But I will say, when on the track, I hated the 3.09 1st gear. Probably cause I was also running a 4.56 rear end gear. Seemed like a blink after launch I had to shift. At that point I had not even mentally recovered from the launch. FWIW.
