So.... this is what we ended up doing...
Just wanted to report back with an update.
We ended up using these puch shoes with modification listed below.
We ground about 1/16" off of the top of the pin end with a cutting wheel - and about 0.5mm from the end that goes against the pin.
We used the springs that came with the shoes.
That worked and we drove the bike around all weekend in the Pittsburgh rally down some very very steep hills.
The suzuki shoes didnt work - they may work with some fiddling around with also possibly.
I attached photos of what we did.
