Well for years Ive seen these funky
and common 5 speeds in volvo cars
and wondered if they where a good
option for an a series being small
strong, compact and cheap.
I then a few years later found some
old ads for volvo gearboxes to suit
A series setup speedway midgets and
recently spoke to a dude who used
to do them for some of the racers.
He no longer has any of the adaptor
plates but its interesting to hear
they used a volvo gearbox as it was
bullet proof, easy to get and cheap.
This guy is gonna get back to me to
see if anyone has the adaptor plate
to suit as there where quite a few
of them and the only issue is that
they are a 4 speed with electric
overdrive but an easy setup with
a button or switch to engage the
overdrive unit so you have another
set of taller ratios for the freeway
or for going backwards efficiently :)

I hope I can get such an adaptor
otherwise I will pursue the bw T5.
