Old Magnet Or Any Other Knowledgable Cat Person. Would You Be Abel To Tell From A {sometimes Reliable} Old Magnet Source If The Transmission Gear Selector & Steering Clutch Controll Levers &linkage Would Be The Same 0n Serial#42a8712 Which I Own And Serial #42a5070 Which Junkman Jess . The Previous Owner Removed These Parts And Missplaced Them My Parts Book Starts With Serial #42a5918 And Up So I Am Not If They Will Interchange Any Help Or A Parts Source Would Be Appreaciated. Thanks In Advance Dan

I have the same parts book you have and not the earlier one. I do have the 933 42A1-up Service Manual which I believe covers up to 42A6674 at least (that serial number is written in the manual).
From comparing illustrations in the later Parts Manual with the Service Manual it appears they are the same. I'd say it's a pretty sure bet but a check against the earlier parts manual would be advised.
