Minnesota is a big state, but it looks like you are hoping to find a place near the Twin Cities. I had used a shop in Brainerd for the driveshaft on my '51 F-1 decades ago, and a quick Google Maps search shows they are also no longer there, so not much help. Since moving to the Red River Valley, I have probably had a dozen custom driveshafts made or modified by Grand Forks Welding and Machine over the past 15 years or so. Great bunch of folks to work with. I am sure if you provide end type specifications, and dimensions they can make something and ship it to you.
