Rear Differential
I have a 1964 f100 with what I assume is a Spicer 60.2 rear diff. It has a rear cover that has 10 bolts and has a drain plug on the bottom of the hogs head. 60 is cast into the housing. It has 4:10 gearing and limited slip. I would like to change the gearing to 3:54's or something near that ratio. Anyone have any ideas where I could get a ring and pinion for what I feel is a not to common rear end for this truck? ND would you happen to be able to help me out part number wise?

And there's another: 1966/69 F100's were available with the optional Dana 60.3. It's not the same as the F250's Dana 60 or 1963/66 F100's Dana 60.2.

My local CL advertised a drum-to-drum 60-2 with 3.54 for $200 last week. It sold pretty fast it seems, or I would include a link. This indicates some are still around at reasonable prices.

Well...now that I've inspected everything including axle shafts and spider gears, my swap to 3:73 is looking more like upgrading to later model 35 spline axles, spider gears, and what the heck may as well go with a posi unit. All can be had for about $1,000.00...in parts...Then of course the front axle will need to change ratios to match the rear and the snowball continues to get bigger!! LOL
