I have a SROD in my 1981 F-100 and the other day I went to add oil to it and mistakenly removed the plug on the drivers side and heard parts dropping in the tranmission case. I don't know what I was thinking as I've had this truck for over 16 years and have added oil several times in the past.
I pulled the transmission and have it on the bench but need a parts diagram or disassembly proceedure to tear it down and put the reverse pawl back in place. Does anyone have an idea where to look for what I need?

Thanks,
Capt Ron
