I have the original wheels on my 48 chevy half ton truck and I will be updating the rearend and suspension with modern components (mustaang 2 and camaro rearend) the updates will use a 5 lug on 4 3/4 bolt pattern. Is there anyway possible to use my original 6 lug wheels on this truck maybe through an adapter or spacer and if possible what is the widest 16 inch tire I can use on the original wheel. Also, I would like to use radial tires.
