Got some new wheels: Boss 338's in 20x10 and 20x8.5

[71'tahoe]

So I was at the swap meet yesterday and the salesman knew axactly what I was talking about and said they'd be ready soemtime next week he was from missorui(spl) Then said well you can add spacers..I said no I dont have room for spacers. He said well it was because the dust caps are from cheap places like advance auto and auto zone..I told him it was becasue the rotors needed turned down at the center where the wheel was slide over to center the wheel. He again said run spacers. At least he knew the wheels were being retooled..and had some what of a date..

On a side note did any one else try these on a 88-98 truck..I saw someone posted they wouldnt fit there either..I wold love to get a set for my 91 shorty project..
