Is there a difference between model 85493 and 85493B motors?

[Harte3]

I'm looking for a service/repair manual for a 1974 85 Starflite 85493B. Manuals for the 85493 are available. What difference does the "B" designation make if any?

Thanks in advance!

Mid year parts/engineering change of some sort. Will usually affect the parts manual somewhat, but the service manual should not change.

Thank you!
I thought it might have to do with a model run as some of the suffix numbers/letters indicate.
