Great job! I just discovered your build, and your walk through and explanation to great detail of your short bed conversion has given me a kick to the behind to carry on with some of the projects here at home!
Great job on the Land Cruiser, I grew up with a diesel '82 on the ranch back home, and there were a few occasions where I wished I had a turbo!
As for rims, I'm thinking if you can find just about any beefy 8 lug rim where you can fit on the 2001 and up HD GM center caps that would look pretty cool!!
