Help decoding numbers

I just bought a 69 convertible 4 speed and need dome help. I can't find the codes listed for mine. The codes on the bottom of the rear end housing are, OHJ 292 W. The J is VERY close to the H. So close that the lower part of the J is in between the "legs" of the H. The casting number on the right side close to the fill plug is 1237. The other casting number is 464910.

The numbers on the tranny are 19W368379, R9S.

The hood has the 427 emblems and "APPEARS" to be original.

I appreciate any help!

I have decided to pull the 350 and Muncie to install a 434 SBC, Tremec 6 speed. Sending the diff out for an upgrade. I will start a build thread.
