Torque Converter / Shift Kit and Shifter

My restoration project is a 65 /6 Barracuda. #1 I'm "hot rodding" the 225.(I have all the bells and whistles, headers, Offy intake, ect.) #2 8 3/4 L/S rear end. #3 My dilemma...I'm keeping the A/T, but have been unable to (and I've have looked...all I see is for newer stuff) find a torque converter. (Street/Strip) My Transmission is a A-904-G. I'm seeing the same responses for shift kits and shifters. (for newer stuff) I had planned on going through the transmission and installing a shift kit. I looked at "transbrake valves" but again I'm see application problems. My intentions are to drive the car, (limited) have a little bit of "street fun" and visit some local tracks. I'm sure someone out there has done the same thing. I've finished tying my sub frames and I'm ready to get after the drive train. Guidance please!

1962-74 Chrylser Automatic Transmission Codes website shows the A-904-G was used behind 1968-71 slants (170, 198 and 225).
I don't know /6 versions but I would think that internal components (valve bodies, shift kits, etc.) and torque converter fitment would be the same for both slant and V-8 versions.
I would think the same would go for shifters.
Isn't the only real difference in the bellhousing to mate up to the slant?
Again, I've never had a slant and don't know for sure. I'm certain others with more knowledge will also reply.
