I have a question about 1950-1952 Champion and Commanders. In 1950 they used a frame with a 113" wheelbase, From my understanding the same body (dimension wise) was employed but the wheelbase grew to 115". Where did the increase in the wheelbase occur? Was the frame length increased or did they just increase the distance between the front and rear wheels?

In 1950 the champion wheelbase was 115" and the Commander was 120". In 1951 the Commander wheelbase shrank to 115". I am going from memory here since I don't have my reference material handy here at work. I am not sure where you got your information.
I could not tell you where the Commander was shortened in 1951 but I'll bet someone on here know the answer to that.

The 1950 Champion is 113". I got this from multiple references and an actual measurement on a 1950 Champion frame. The references state that the Champion and Commander went to a 115" frame for 1951 and 1952 but I'm not sure how this was possible if they were using the same bodies as the 1950. The only way I can see a length growth of 2" is to move either the front axle or rear axle or a combination of both. Since 1950 and 1951 were both the bullet nose models I really don't see Studebaker making major changes to the body due to the high costs of retooling.

The difference in the 50 and 51 champion frames were that the front chassis rail horns protruded past the front bullet nose panel whereas the 50 stopped short before that panel.
there was a difference in the wheelbase too but only slightly.
The 51 rear axle was 1" or 2" farther back this may have been due to a spring pack change at that time.
From my observations the 50 that I had the springs were wrapped but the 51 were not, they had liners between the leaves.
I also measured at the time that the axle was set back farther from the front rear spring mount.
When I placed a 50 body tub on a 51 chassis the difference wasn`t even noticeable.
All the body mounts on the 50 starlight body matched the ones on the 51 4 door chassis
