1973 duster fit 20"s??

Personally, I think if you wanna go with 20s, go with 20s.

I've got a set of Dodge Magnum SRT8 20s waiting to go on my Intrepid within the next few weeks.
They're factory wheels made by Mopar, so they are more low profile and less "LOOK AT ME!" bling.
I can't wait.

However, my Dart will get no such thing.
As a matter of fact, I kinda like the 14'' Magnums that are on it now.
I'll probably still upgrade way down the road, but it won't be to anything bigger than 18''.
However, thats just my opinion on muscle cars.
