I am in the process of doing a similar conversion. I am installing a 62 235 with an open drive shaft SM420 in my 1939 JD (3/4 ton). I am using a 49-53 bell housing. I will need to fabricate a bracket to attach the pedal assembly. Instructions for bracket are for big bolts and somewhere on this site. Don't remember where but I have copy of the bracket plans. attached are photos of progress to date with casting # of bellhousing.
