I bought a replacement driveshaft for my 4wd tracker, front shaft (propeller shaft is what it is technically called as but it is just a driveshaft). Even though I gave the seller my VIN so they could make sure I was getting the correct part, it was still not correct. The seller didn't even want it returned, so I had another piece of metal hanging around just taking space. I decided to try to modify it because my choices are dwindling, and a new custom driveshaft would be pretty expensive, And I thought I may as well film it.
