Big saloon/TR gearboxes and thanks for the info Randall. Are the same applicable to the smaller Spitfire/Herald/GT6/Vitesse gearboxes ?
Also, while I'm thinking relatively straight, can the 1600 Vitesse 6 (Sports 6) non-o/d mainshaft be replaced with the o/d mainshaft and d-type overdrive from a Spitfire Mk1 -Mk3 o/d gearbox ? FWIW part numbers for Vitesse 1600 and early Spitfire overdrive mainshafts appear to be the same (o/d mainshaft part number for both models = 208142 and d-type o/d unit part number for both models = 306553). The Vitesse 1600 ( Sports 6 in USA) gear ratios seem to be much closer together than the Spitfire (Mk1 - Mk3) gearbox gear ratios. It would seem beneficial to use these ratios with the Spitfire four cylinder engines. Am I correct? Might be possible to use the Vitesse 1600 gearbox in the Spitfire4 (aka Mk1). I know the bellhousing must be changed to the Spitfire type. Anything else ? Pro's and cons ? Not sure how the Vitesse ratios will affect power, speed and fuel consumption of the early Spitfire.

ORS in the UK will do it for you, but it's close to the cost of a new shaft. Randall "This e-mail is sent in terms of the following policy/disclaimer.
