Hello I have a 1947 3100 half ton with a 1955.2nd 235 engine, the 1947 bell housing, and has the original rear end. Later I plan to swap it out for 3.55 to 1 ring and pinion.

'47 could be non'syncro 4 speed, a good trans. But 420(synchro) would be more useful. Price sounds high.

That's an SM-420...
L292 is the date code
L = December
29 = Day
2 = Year (1952 or 62 ???), that casting number was used from 1948-63.

So it is synchronized? Would it bolt up to the ‘47 bell housing?

Novak in SLC make kits for 420's, although some synchro are no longer available.

Those are good transmisisons, but I wouldn't pay $350 for one unless it was rebuilt and comes with the paper work and a warranty.

Being for a torque tube rear will add a little (they are a little harder to find), but not three to four times as much!
