Jorb . I'll try to answer your three questions first and may be able to send some detailed photos
By the cast numbers it should be a 37 truck
I purchased the bearings on eBay and am relatively sure they are 595005 and 595007 the odds and id's match chevrolet dimension
The rubber seal came with one of the two sets of front and rear bearings I purchased on eBay. Because they were so cheap, I purchased two, the second when the first sets ods seemed to large for the id of my torque tube
I haven't pulled the drive shaft so I'm estimating the id of the torque tube. It's close to 1.5 and might be a little larger, but not much. The od of the torque tube is 1.73, so if the tube thickness is 1/16 than the tube is 1.73 - .125 or about 1.6. The rear bushing od is 1.68 so it's .08 larger. That would be a hard push into the tube, if at all.
The front bushing is 1.72 and if i can get you the picture, you can see it od is the exact od of the torque tube.
Right now I will send this post and figure out how to attach pictures in the next post.
