My post TS-6000 has a TR4 overdrive gearbox.  About all I recall doing 
is elongating the rear mounting holes and using the TR3 shift leaver in 
the TR4 gearbox. You will need the next length longer bolts at the 
bottom of the bell housing because the lip on the TR4 transmission is 
wider then on the TR3 transmission. This will also require you to 
readjust the clutch slave cylinder rod.


  I've no experience with the TR6 box.  The gearbox mounts are farther 
to the rear than the TR4's mounts. You would need to bend down the 
flange on the TR3's cross member and drill new holes.
