Upgrade to a 4-synchro box

[Paul-Ernest Levesque <pelevesq@globetrotter.net>]

Hello!!!
I own a Spitfire 1970 MK 3 with a 3-synchro gearbox, how complicated is it
to Upgrade to a 4-synchro box,(I mean buy a new 4-synchro box for
replacement) in reference to drive shaft length bell housing etc. the actual
gearbox need to be rebuilt and Spitbits sell a standard one for $450.00 for
a 3-synchro I think. Any comments
Have a very nice day
Paul-Ernest
