Schumacher mi3.5 questions

[OneKiwi]

I got a roller with some defects that I am looking at maybe buying those bit I need but it seems quite expensive.

My front dogbones seem to be after market, the pins are about 2mm + wide, not the 1mm that fits with the blades.

This is is eating up the out drives and they now need replacing.

Is there a blade with a larger hole?

Do the dogbones from the mission/mi1 fit?

What parts fit this car? From what other cars? Mi2/Mi3/Mi4 etc

Thanks
