t5
Not sure if this helps, but I put a mid 80's richmond 5 speed (T5) in my 70 chevelle BBC car,about 5 years ago, it came with a shifter, and it was a fine spline so it went into my clutch, pressure plate set up w/o any mods but the cross member did not line up and I fab'ed a mount and put a little bigger hole in the floor, cannot remember about length of the trans and if I had to do any with the drive shaft
I also think that these trans are not as robust as I would like but I do not beat on the car at all so it has lasted so far.
I paid 275 for the T5, shifter and and attached bell housing
Hope this helps
