Correct, now the car is running well it would be nice to be able to keep the
revs
down on those longer runs!

The gearbox I have is sweet, very smooth in all gears, In some ways it would be
a
shame to get rid of it, but if it was a swap for another recon then I could
handle
that..

I would like this option, but I think I would be inclined to let someone else do
it...
Mind you this would be the first time I have let anyone else touch the car!

Yep these ancilaries seem pretty easy to get second hand, its just the overdrive
itself which I'm puzzled about..
Do I buy one from the TSSC back pages and then get it reconditioned myself, or
buy
a recon unit from one of the big suppliers? can an overdrive be worn beyond
repair?

Yeh this is a bit of a bugger as I have had the body off and that would have
been
an ideal time, but cash was limiting, and it was overdrive OR respray! needless
to
say the paint was quite important..
