Hello NHluvstruck,
Thank you for your prompt reply and interest in helping me with my Chevy rim search.
As it turns out according to the Chevy P/U Shop Manual(`48 to `51) the 1/2 ton pick-up Model: 3100 could arrive at the Chevy dealership with two possible tire/rim configurations:
(1) 16" rims w/6.00-16-6 ply tires.... or .......
(2) 15" rims w/6.70-15-6 ply tires
In my case I have the 15" rims w/relatively new 6.70-15-6ply tires so I am stuck with finding "GOOD/USED" 15"X5" RIMS.
Thanks
