Kyosho knuckles and carriers are easily swapped for YZ10/870c pieces. Not sure about drive shafts but that shouldn't be too hard. The reason for kyosho is that I based the ideas on the A-Main Bullet FWD that I also am still in the process of finishing. I won't adapt something newer, that doesn't fit with my era correctness that I require on my builds.
As far as the tensioner, it would be best to tension the slack side of the belt, which is the top. That doesn't help clearance but when I get a better pic you will see it's not rubbing nor is it as close as it looks. Being the tension side it gets further away under accel as well.
Thanks for all the comments, this will be a kit soon- it's a matter of getting the pieces made in quantities of more than one at a time now.
