Any single wheel conversions for the Tamiya kit?

Do you mean a vehicle with just a single rear axel instead of the dual? If so, I have not seen nor heard of one.

I assume you mean to convert the GMC to a 1 & 1/2 ton 4X4 Chev. If so I have not seen or heard of one. If you do a conversion of it don't forget the bonnet side panels are different between the two types.

Nope, 3 axles with only 2 wheels per axle. No duals on the back. There was a shortage of tires in the ETO so the wouldn't use the duals.

Don't know of any conversion kit unless you want to try and use the revell (M34, M35 whatever)2 1/2 ton kits suspension. But doing it yourself shouldn't be that hard. On the real thing dual wheels are just that 2 wheels. No inside and outside. On a model the inside wheel has alignment tabs or holes to help you mount the outside wheel correctly. The outside wheel has the lug and lug nut detail. If you want to mount just one wheel you need to remember that the lugs are long enough for two wheels. You will need to add this detail to the inside wheel. You could use the outside wheel but you would need to remove the nut and lug detail so it will mate flush to the axle Why? Because if you mount just one wheel on an axle you need mount it as it was designed, that is with the mounting surface of the wheel to the outside or the way the inside wheel is set up. represent the correct length of the lugs with the nuts tightened down on the wheel. Did I say easy? No but it's doable.

Steve - if you want to model one of the "singled-out Deuces" from that time period, may I suggest using components from Italeri's DUKW. This truck chassis is an example of the singled-out Deuce.
