I am new to these trucks. Just bought a 1955 1st 261 and want to raise the differential gears. Possible to something in the low 3s. Looks like a 10 bolt but when I look a the internals on line for the 10 bolt they looks very different from what I am seeing, ie the adjusting nuts etc. Can anyone help and is this change beyond the capabilities of someone with only moderate skills?

I can't tell what , by name, differential I have or if it is original, certainly looks to be.
