55.2-59 1959 Napco Wheel Question

[Steveoreno]

Guys, I understand that the Chevy 1/2 ton Napco came with 16" wheels standard...maybe 16 x 5.5 and they had three hubcap retaining clips. I just found a set of 16" x 5" 6 lug wheels that came off of a 1958 Apache 2wd....they have three hubcap retaining clips but are drilled for 6 clips (see attached). The truck they came off of was a one family owned original from Idaho. So my question is.......is there any reason that I cannot run these wheels on my Napco with 7.50x16 tires. I did note that the center hole of the wheel will not clear the washers on the lockout retainer bolts...I may have to file and index the washers. I thought that any 16" wheel with 6 retaining clips was for a car....just want to make sure that I will be OK with these. Thx.
