[Fot] O/D Gearbox

[DAVE HOGYE]

Yes on what Chuck said.  That is the common failure of the earlier non-syncro first gear transmissions.  Especially for racing, the later case is a must have.  But you would still have the o.d. issues.

p.s. if you have leaks, as a last resort, try to catch them with absorbent material and not drip freely to the pavement and race track.

It's been welded before, so additional welding is not looking promising. Like most A type units, it leaks like a sieve and this one seems to only intermittently engage. Therefore, I'm considering going to a 5-speed set up. Any experience with either the HVDA (Toyota based) or the Vitesse (Miata based) units? I'm a fan of originality, but I'm also tired of fighting the fun of O/D units and the fact that getting one properly rebuilt in the US seems to be very difficult.
