Apologies, Jamie
I thought someone with better knowledge would come back on this, but you are stuck with me.
This is what I think I know, but it may be wrong.
When they changed to low frame the engine was mounted lower down in the chassis, so the feet of the crankcase were moved up to make this happen.
Which means a high frame engine in a low frame sits a bit high.
And a low frame engine in a high frame will be too low, by my logic - but I am sure I have read somewhere on the forum that you can't put a low frame engine in successfully but surely it just needs jacking up a bit?
So, as you can see, I am confused.
Also, as they changed from three speed to four speed and from short chassis to long chassis the engine moved forwards a bit - again done by re-positioning the foot mountings.
I think.

I have not put a picture in before, if this has worked you will see a pic of the "stop" on a high frame crankcase - the noggin sitting on top of the starter bulge, which in a high frame is hard up against the back of the starter mounting flange.
I can't find my pic of the low frame 'case - but the "stop" is a much more obvious squarish lump about 1" back, away from the mounting flange.
Clear as mud?
Cheers
