Hey guys are those Richmond's the same size as the tremec tko
for length here are the overall lengths to the end of the tailshaft
Muncie 4 speed (pre 71)= 21.5 inches
Borg Warner Super T-10 = 23 inches
Borg Warner 4 speed = 22.61 inches
Richmond 5 speed = 21.57 inches
Richmond 5 speed overdrive = 21.57 inches
Richmond 6 speed overdrive = 21.57 inches
Tremec TKO 5 speed = 30.4 inches (GM)
Tremec 6 speed = 33.0 inches (GM)
As to size of the transmissions Tremecs tko's require complete removal of the entire factory tunnel in 61 to 64 Chevy's and 55 to 57 chevy's (floorpan) and raising the full length and width of the tunnel in front of the seat around 2 to 3 inches.
Note the significant difference in lengths to Richmond transmissions, Muncie 4 speeds and T-10 4 speeds
There are
Long 5 and 6 speed shifters sold for and with the Richmond transmissions.
