Hi! I joined the site so I could talk to you first! Since I am a healthcare professional and a wannabe old car guy that has to hire most of the work out, I need to ask for some clarification about your post (not safe for me to make assumptions...). When you said, "
"I've heard you can go with a ford ring and pinion from a 87-93 econoline that will fit. My notes tell me to look for ID E5TW4210BJ which is a 39/11 for a 3:55 ratio. This might be what I look for also. I have a 3600 with the same basic set up."
did you mean you can just replace the existing ring and pinion gears in the stock housing, or did you mean that you needed to change the entire rear end?
I have a 50 3600 that I bought for my wife that has 456 gears in it. I also spoke with Patrick's Old Cars and Trucks (what a great guy; he was really [censored] at his phone answering machine when we were chatting...) and he gave me the exact same set of numbers. What I din't knows if that is for the whole rear end or just what is stamped on the ring or pinion gear.
I have located an '87 Ford E250 rear end complete with brakes that I can purchase and have shipped to my mechanic, but if it is really just a matter of changing the ring and pinion gears ONLY, I might be able to save considerable bucks on shipping.
What did you actually do with your truck? Thanks a million for any clarification you might provide.
