What is the '33 Master driveshaft diameter at the front bushing?

I removed the front bushing because I could feel up and down movement of the driveshaft. The old bushing ID is 1.030". It had the original cork seal so I assume the bushing and seal are original. The new bushing obtained from the Filling Station ID 1.030" (same as the worn original) is a Billy Possum brand. If the shaft is 1 inch dia. as I suspect. .030" is too much clearance I think. Any thoughts or info. are appreciated.

Thanks. If the bushing is 1.035 then the shaft must be 1.030 when new. I just talked with Skip Geear and he said that my drive shaft is probably worn. This is not what I wanted to hear. The seal supplied by the Filling Station is curiously for a 1 inch shaft. I might try an Okie bushing if they are available and would fit a '33M. Do you know of a source?
