What do these numbers mean

Hello. I have a 1979 CJ5 and today I heard a loud clunk when climbing a hill in four low. It sounded like the Transfer Case was jumping teeth, BAD in 4 low and not as bad in 4 hi. Every thing seems fine in 2 wheel drive. I noticed that I have the two top bolts loose/missing where the Transmission bolts to the bell housing which could maybe be part of the problem. not for sure. I have found that Im pretty sure I have a Dana 20 TC but the only numbers I found on the Transmission are E-CA-QU and 2503347 as best as I can make them out. I just got the jeep and know very little of the beast. Everything I have need in the past I have found here from searching.. Thanks for any help and/or advice.
