manual box conversion

[WAREJEFF@domain.elided]

the stag manual box uses a one piece housing for both the gearbox and clutch 
bellhousing. the stag utilizes an adaptor plate of about a 2 inch thickness 
to adapt the gearbox to the back of the stag engine. i am no expert, but 
attempting to adapt a different gearbox to work on the stag would involve 
considerable engineering and machinists skills. the stag manual box is very 
similar to period tr6 gearboxes, with various modifications however. i belive 
the sd1 uses the rover 3.5 engine with 5-speed, similar to a tr8. i HAVE a 
tr8, and would never attempt to adapt a tr8 tranny to work in a stag. the 
stag had some design imperfections, but if properly maintained can be nice. 
modifications are more trouble than they are worth in my opinion. jeff ware.
