I have one here I got from an auction, been modified for I don't know what, I remember looking online for info, and the casting number came back as a 1957-1964 pig, looks freshly rebuilt, has "4.10" written on it by the fill plug, as I remember the info said it was basically a "742" before they were called "742". So apparently the ring n pinion, pinion spline, etc would be the same as this one. It has what looks like a brand new yoke, as I remember it takes the U bolt type u joint retainer. (it's stashed away)
It's open, no sure grip. I'll have to dig it out and get that number off the pig.
