Correct Rims--1968 K10 SWB

[Dave K.]

I want to get rid of the ralley rims on my K10 and the 33" tires and go back to either stock or slightly larger (31") tires on stock rims. I need details on the stock rims and also perhaps a source? Any help would be appreciated! If someone close to Milwaukee Wisconsin knows of some please advise. Also, what would the stock tire size have been on this truck? SPID doesn't indicate anything on that front.

Thanks, Dave.
