Phil,
My 3 - Richmond 5 speeds are all 1- to 1 in 5 gear( not made now) . One was $1000 with Hurst 5 speed shifter ( from J.Yoeman) and the other two were $2200 to $2400 each ( one used and one brand new - never used). Using 3:08 or 3:36 posi’s in my 62’s
They are the same length as Muncie and BW 4 speeds - Hurst 5 speed Richmond shifters mount in factory 4 speed location on floor pan & factory 4 speed tunnel cover.
About 2700/2800 RPM at 70 mph with a 3:08 posi with 27 inch tall tires...
First gear in my Richmonds are 3:28 vs Muncie 2:54 1st gear, the lower first gear makes the 1 to 1 5th gear with 3:08 posi or 3:36 posi work.
My Richmonds are 21.57 inches long compared to Muncie or BW at 21.50 inches. The Richmond overdrive 5 or 6 speed‘s to my knowledge are also 21.57 inches ( from bell housing mount to back end of the transmission)
The new Richmond 5 or 6 speed overdrive will fit the factory shifter location within 2 inches( back 2 inches toward the seat) of the factory 4 speed tunnel locations ( I have pictures). I use them because they “do not require floor tunnel modifications for 61 to 64’s and they shift like Muncies...
They only sell a Long 5 or 6 speed shifter (to my knowledge) for the overdrive Richmonds.
( I have pictures of the Long 5 speed shifter in a 62 impala convertible with a 5 speed overdrive Richmond( plus I know of a 61 with a 6 speed overdrive Plus a Jim Yoeman switched his 62 bubbletop with a bench seat to a 6 speed overdrive Richmond just before he sold it - so I know they fit).
The Long shifter body does sit about 1 to 2 inches taller than the Hurst 5 speed shifters I have on my 62 SS Hardtop and SS convertible using my factory SS shift plates ( using Hurst foldable boot...on top of the factory 4 speed tunnel cover )
Actually I now have a extra Richmond 5 speed sitting on the bench - I may use it in my 62 Impala 327/300 HP that now has my Muncie 4 speed with overdrive in 4th gear....
I do have an extra Long 5 speed shifter for a Richmond with 1 to 1 5th gear.
