Those 6 lug steelies are your 73-80? Stock 4x4 chevy wheels Posted using the Full Custom H.A.M.B. App!
mini truck 6 lug fit the GM bolt circle. Datsun,Chevy luv ,Ford Currier etc 6 lug wheels swap onto Gm 6 lug pick ups.
....oops! I forgot about the dodge D50, however I dont think thats a dodge D50 wheel. 6 lug dodge dakotas wont fit either as they are a smaller 6 on 4.5 bolt circle and wont fit the 6 on 5.5 GM trucks and/or the trucks mentioned above.
I really dont know what they are from - that's why I said "I think". Maybe a trailer wheel? They don't look like a GM wheel. Look kinda like these - same size. I paid around $35. I got them because they have that OE look with the small openings at the hoop area http://www.trailertiresandwheels.com/15x6-6-lug-black-conventional-steel-trailer-wheel http://www.dexstarwheel.com/products.html
They aren't the worst thing ever, I have them but skipped the center and ran a thinner trim ring. I just can't do the centers.
