[AJD] John Deere GP

[Chas. C.]

Thanks Paul. If you can locate them I would like to see some pictures of 
what it takes to do the final drive.
I don't have a compression tester but I think know who does. We have a guy 
the buys and sells and restores a lot of old tractors that lives just a 
little ways from us. I shall check with him.
Now, what illness are you talking about? Hope your back on the mend now.
Charlie
