Not sure why the P/O did some things. He had even taken the steering column apart(lost a lot of parts).The old wooden plug had been there for some time. I did not even notice it when I put the tranny in originally. The plug was painted the same color as the transmission and did not stick out very far. Will look at the tranny more closely to see if any further stamping on housing to check manufacturer, etc.
I have already verified that this is a 3/4 ton 8 bolt wheel 5.14 rear end truck. The 5.14 rear end and 4 speed tranny were options on the Hypoid GMC H-050(3/4 ton) per the GMC Maintenance Manual I have. Had already verified the rear end ratio early on since I had to put it back into the rear axle housing along with axles, etc. Looked up the Serial Number and also verified that it is a 150 series made in mid 1949. The drive line has a torque tube back to the carrier bearing and open shaft from there to the rear end. I am fairly certain that all above is correct, but would not be the first time that I missed something on this project. I have had to start from scratch on this one since almost everything had been disassembled and moved a few times before I bought. The second truck that I had bought for parts was pretty incomplete also.
The speedo spins up and seems to be working ok. Not real concerned about accuracy since I plan to keep the 5.14 rear end and just cruise local streets. Doubt that I am in risk of getting too many speeding tickets with the set up that I have. If I upgrade rear end or tranny, will definitely get speedo accurate. Right now, just working toward actually pulling her out of the shop under own power. I had nothing above the frame when I started, so still have truck on dollies with last section of driveline still not installed. I will put that in in next week or so when I need to pull truck out to paint doors and fenders. Right now I have the cab, inner fenders, and some stuff hung on the radiator supports. All outer fenders, doors, hood, running boards, etc are still off truck waiting for final body work and/or paint.
Thanks
