Adrian,
The post '74 Midgets used the Triumph 1500 engine/trans from the Spitfire.
Whereas the Sprite/Midgets never offered overdrive (despite having advanced
unibody construction) the Spitfire had the optional sophistication of having
an overdrive trans available (despite having an antiquated frame/body
construction).
There are varying opinions as to exact interchangeability. From my
experience the D-type three rail overdrive can be swapped directly for a
non-OD single rail trans (did it in my '73 Spitfire 1500). Will it work in
a Midget? Don't know. Depends upon the trans tunnel clearance and if
there is a real difference in drive shaft length for the three rail/single
rail transmissions, overdrive or non-overdrive.
