Thanks for the suggestion, Rick, but the shifter lever is in the correct place - the only issue has been height, as the toploader sits too low at the back with the tailshaft pretty much resting on the crossmember and being too low to give the correct relationship with the diff flange.
I reckon the toploader mount flange is at a different height from that in a T10. I have the correct T10 mount on the chassis and I need to space this up by around 3/4". I know Nick sells a spacer for toploaders that lifts by about the same amount, so I'm not the first to find this. An ally block spacer mounted on top of the rubber, with longer bolts through the metal strap and spacer, should sort my problem OK. If not I'll be back on here quick!
