I just bought a 1949 Chevy 4400 grain truck w/o a hoist. The owner said that with the lift at the elevator and his 10 kids that he just didn't need the extra expense. This truck is all original except for a 1950's insert bearing 235, from original owner. I even have copy of original 1949 title

Can't wait until spring to go get the truck out of the snow. My question is this:
I have the ability to get a hoist and pump for this truck to convert it over to a dump bed. It has the original sm420 in it but no pto. I need to know what pto will fit. Have a few that I can purchase, but don't know what brands/numbers I need or what to look for in a used pto. Sorry if this is already in a post, I just couldn't find this information anywhere. Thanx
