Info.Request.

Hi Bob. Bother? No bother. Heck I thought that was why we're all here. Not to bother, to share our B.S stories, ask questions and help answer questions.
Yep, the "S" means special, that's what makes it a 'Cuda. New Process made the transmission, it's an A-833. Hurst made the shifter. The A34 means Super Track Pak. That's a good option. Dana 60 axle, 9.75 ring gear, 4.10 ratio with sure grip (like POSI, only better), power front disc brakes, max. cooling, 7 blade torque drive fan, Hemi suspension, N/A with air conditioning.
If you look on the side (pass) of the trans., you might still be able to see a 677 stenciled in yellow #s about 2" tall.
P.M. me with your fender tag info and we can go through it if you would like. Did you see the rear ends in the tech section? Hope this helps. Ray
