Help identifying differential

Can someone help me identify the code for the rear end I have. It's supposed to be a 1973 F250 Spicer 60 3.73 ratio. Thanks

Thanks looks like a 68 not a 73. I have it installed and brakes redone. It has the same size u joint 1310. Had to shorten the drive shaft 2-1/2".

I think the 68 would be a better fit. Didn't the track width get wider in 73?

Everything lined up on the 68 rear end. The brake line block had to be changed because the original 68 had the hose built into the block. I had a block to accept a new hose.
