Freewheels

I'm looking for replacement freewheels, can anyone tell me the part numbers for GMN or Ringspann freewheels for my 86 430AE?

I've read GMN FE438Z and FE473Z but would like to know before ordering.

The 4 speed has 38 58 and 78 . Have you got yours apart to measure ?

It looks like they ditched the smallest set for the 3 speed
meaning youd need 3 of 58 and 2 of 78 to do everything.

Measure the id of the gear that the outside of the bearing runs on

Thank you, I'll have to dig them out after our interstate move recently.
