Most times the center section, or "pumpkin", or what is the actual differential is a 3.90 in the earlier trucks. One might get lucky sometimes and get another gear. Especially if it is an Automatic vehicle.
I recently was given a 59 rear end and what a surprise when I pulled the cover and found out it was a 3.08. You just never know.
Around in my area a junk yard will want as much as a couple hundred for the rearend but you won't know the gear ratio. I've got a 3.90 center section you can have if you want it but it whine's going down the road. If you want it and then change ring gear/pinion send me a PM.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
