New RFF motor install advice

Im going to install my new Ride for Fun motor this week. I heard that this would be a good time to replace the bushing on the input shaft. Recommendations on that and where to purchase the part would be greatly appreciated. Thanks in advance.

Polaris/Golf cart dealer for OEM “circular style” that fills into the splines when broken in or nevaccessories for cheaper but slightly incorrect 10 spline bumper.

Just ordered it, thank you!

Don’t order the NEV one. It’s junk. I bought 2 and they both had to be replaced within a month. The round smooth one from Polaris is going strong 5 months in.

I just ordered the Polaris one, thanks for the input
