Identify this 14bolt FF.

Hope these will help between the backing plates is 54 inches give or take a lil and from outside to outside of the leaves is 45 so center to center should be like 42?

Cool, I'll be more serious about getting it measured now to see if I can use it in my 3/4 ton 2wd's or K10 / K1500 for the K10 to K20 conversion.

I tried to count teeth on the pinion of this thing. To hard to see in there behind the carrier and ring gear. So I got the drums freed up for the spin test. Confirmed, it's a 3.73 ratio.
I also took a couple measurements on the axle tubes to the perches and compared them to my 84 3/4 ton. Seems this rear end WILL bolt into my 3/4 ton trucks, which means it'll bolt into the half tons too. Nope, Not for sale now. I'll be keeping it. Thanks for the ID help dudes.

OMG, I so hope you guys are right. I'm getting a fuggin hard-on right now. I've had the cover off before, and didn't tighten it back up, so I'll damn sure count those pinion teeth to make sure. Oh boy would I be happy. That would mean I can use that rear end in my K1500, and convert the front 6 lugs to 8 lugs and be ready to rock n roll.

Or you could buy my hub conversion, disc brake that biatch and stay 6 lug......lol.
