Not really an answer to your question, but this vista g1000 of Dads was sold out of A & P Motors out of Dutton Montana. I believe this was a large MM dealer back in the day. Dad bought the tractor from a john deere dealership in south dakota around 1978. The A & P Motors sticker was on the side of the dash and front hood. The tractor had .60 over M&W pistons, and cat airfilter and pre cleaner. We later added the 20" tires it had the large 11.00-16" tires on it back in 78.
