Choosing Seals and Bearings for a 1983 px150efl

Can anyone help me make sure I order the best seals and bearings for an engine rebuild please?

I have a 1983 px150efl. I need a full set of engine seals and bearings, including the primary drive shaft bearing.

I need part numbers for the best quality of the these if anyone can help me I'd be very grateful:

Bearings:

1.      Main Crank

2.      Hub

3.      Flywheel

4.      Selector Box

5.      Primary shaft

 

Seals:

1.      Main Crank

2.      Hub

3.      Flywheel

4.      Kickstart ‘O’ ring

I am preparing a large order for an engine rebuild and I need to be sure I’m ordering the right parts

Thank you,

Simon
