[TR] A-type to J-type !

[David P]

As a side bar story.. I have a pieced together TR6  ('74) that sat for 
10+ years.. mostly out doors. Blown head gasket, live mice included, 
rotten interior and top, shade tree wiring for lighting, etc. etc. Well, 
after getting it running and moved it to the lift I discovered it had an 
A-type O/D, but no wiring, no solenoid, or stalk switch. Today's last 
job is to get the rear end  off the lift and see if it will engage it 
manually. If yes the new owner wants it brought up to par... meaning I 
have to undo the efforts made to the carpeting and all that goes with 
rewiring and relays and... What fun!  DaveP
