I also have a 49-3100 and would like to mount a spare tire under the bed. Question - has anyone used a modern cable crank system for a spare tire? If so what car/truck did you get it from. Also post pictures if available. Thanks.
Done it several times. Wrote an article for Custom Classic Trucks/Hot Rod mag. It was for Panels and Burbs but works for trucks. I used a 1999 Chevy Tahoe winder. Many winders will do. The trick for Panel or Suburban was a fake trailer connector for the crank handle. Made my own crank handle. Most of the "guide parts" made from metal pieces I had laying around. You can see the crank handle in place above the bumper in one pic with the tire on it's way up. Open the chrome old school connector door and insert handle thru and into tube.
