Hi again....
Hoping someone would jump in with some magic answers....
Something I was looking at myself....
Sadly not so straightforward.
The actual wheel boxes (things wiper arms fit on) have a different number of teeth from the older mini to the clubman... (changed about 68/69?)
I think is 22 vs 32
(piccies borrowed from minisport.com.au web site)
Old:
Newer:
So the clubman motor is setup for the 32 - but with the 22 teeth would thus make the arc too big (eg 32/22 is almost 1.5 times greater arc ).
( not quite that simple as arcs are different start with between the different motors - but is close enough to explain the problem!
eg clubman motor has a 105 degree arc -> would become 157 degree arc)
The wheel boxes themselves are physical different sizes (see width in piccies) - so just can't be swapped over either.
(The Tubing might be able to be modified but would have to be measured very carefully and need flaring tool etc (but may be the *simplest* solution))
This was where I got too when I found an old style (square body) 2 speed motor off a Humber Vogue - so should avoid all those issues
(though these are hard to find and thus expensive - but old humbers,triumphs and jags etc may have them)
I don't know about the Rover motors - but think they use the same 32 teeth wheel box - so expect the same sort of problem.
The motors also have a different mounting method - so may need extra holes drilled ???
Whether the tubing is a better fit maybe someone else has some idea???
