A vs. J-type

[Turner & Turner <turner@turner.se>]

Scionissimos,

My ´74 TR6 is undergoing a rebuild. It's non-O/D at present but I'm
going to fix that.

I'd like to put on the A-type because you get O/D on 2nd gear. However,
I know the A-type is far more expensive and scarce than the J-type.

On the other hand, I've heard that in theory, an overdrive unit can work
on all gears. Can the J-type be converted to function reliably on 2nd?

Thanks in advance,
