I've been considering to convert my 1450 to a torsion type suspension, going to a larger trailer-type wheels all together, running like 4 of them, elimination front small idler completely., similar to what 1500s look like.
As far as masters, see if you can see what I did with my 1402, I simply cut/repositioned the control arms, and that cleared up a lot of space for the feet to go in easier.
I guess time will show where we all end up...
First run went well, althou I'm not too happy on how the cat vibes/pulsates due to the track movement, something is either loose, or too tight...
