What about the theory of removing every second stud and fitting 20's with 5 stud pattern? I'll give it a go if no-ones sure and report back?

The Chev 10 stud pattern uses smaller dia studs on a smaller PCD than the regular "wide 5" pattern used on other trucks. And 40's Fords have a different stud PCD to the more common Dodge/Inter truck wheels of the 60's and 70's.

Bob McNeill has raised a pertinent point regarding the spacers for the hubs (or spacing of the rims).

The pre-war 20inch wheels used on Fords and Chevs generally ran smaller tyres such as 6.00-20 or 7.00-20, while later trucks went to sizes such as 7.50-20 and 8.25-20. There are specific rims to suit each of these tyre sizes, and in some cases hubs too. The obvious reason is that wider tyres will require a wider rim, and dual wheels will need greater offset so the wider tyres dont foul each other when "bagged" out under load. But a more specific reason is that the centreline of the front tyre must be in a particular position in relation to the Kingpin Axis for it to steer safely and acheive optimal tyre wear. Putting a large dia tyre on a rim with offset for a smaller tyre will have the contact point in the wrong place. With the contact point in the wrong spot, steering effort will be increased. There was not a lot of camber and caster adjustment built into the design (ie: Nil!) of the front end, so it is critical that the correct combination of bits is used to set it up safely.
