New 20" wheels, right size? Check it out.

[VerticalSmile]

Please help, I want to make sure before I drop all this coin I buy the right size.
I tried to do as much research as I could on this site and this is what I came up with.
These will go on my 1979 Chevy with a complete Air Ride Tech lowering kit.

I'm buying from this place and I included the part numbers below.
