I am considering buying a 871 - year unknown as I couldn't find the serial number over the starter housing. I did see a number on the side of the SOS, but didn't write it down. Have reviewed some of the threads and am concerned (to some degree) about the SOS as I have a Ford Industrial 4400/loader that REALLY sluggish shifting into reverse.
I have a 1958 851 with a 5 speed (an bad engine). I am considering the option of replacing the SOS with the 5 speed if needed. I see someone did this to a 801 in another post - but current owner didn't do.
Can anyone tell me if is possible, and if it is, how difficult (and costly???).
New to forum, so open to critique .
