Want to rebuild my crank in my 440 Liquifire, where do you source the crank bearings & are there rod kits out there for them?

Looking for a pictures of a Magura throttle set up from a Liquidator.

Thanks guys for the info! I want one of the drive shafts with the press on drivers as I'm not for sure on driver size yet. I'm using a .975 lug track out of a mid 90s Polaris.

I have a 76 Cyclone that came with no front track drive shaft & I want to put a hex shaft in it. What length shaft do they come with from the factory? Is there a newer shaft out of another Deere that will get this done for me?
