Don, I installed an O/D in my '79 "B" and it is a easy conversion. You will
need to install a on-off switch for the O/D, I used the gearshift mounted
switch, and wire as shown in the repair manual. No need to change the
driveshaft! MG changed to one length (31.125") for both O/D and non-O/D
transmissions in Oct. '67 (car # roadster 138401 and GT # 139472). The
different lenghts that Porter is talking about were for cars built prior to
this date.
You can call me if you want to discuss further (910) 299-4819 and the change
is very much worth the effort!

>Don, Don't know where you can buy the parts for the MGB A/C now. You'll
have to find a parts car and remove the engine mount, etc. from it. Try to
find a later conversion with the rotary compressor. It doesn't take near the
power to run as the earlier type. If the price is right, I would buy the
interior (evaporator) unit as they are hard to find. By the way, this was
NEVER a factory option, always dealer installed. Regards
