Re: [Amc-list] Fw: overdrive wanted & questions

[Glen Hoag <hoag@xxxxxx>]

AFAIK, the Laycock J-type was the only overdrive unit used in the 
'70s.  I have one behind a 150-T in one of my Pacers.  It was offered 
for two years; 1975/6, after which the T-4 and T-5 transmissions 
became available.  The 150-T for overdrive has a special output shaft 
and an adapter housing to the overdrive unit.

For a Met conversion, I would look around the British car sites for a 
gearbox/overdrive combination that fits the Austin engine, since that 
is what powered the Met.  US products are unlikely to fit without 
much work, though the Gear Vendors Over/Underdrive unit is designed 
to be mounted behind a non-OD transmission, and is patterned after 
the Laycock J-type unit.
