I'm not sure.
But, i'd do what it takes to make them fit, if you could get them.
The reason i'm a big fan of the fox width, is because it's the most narrow. You can always add spacers to make the rims/tires to fit.
With the wider track width, it's impossible to take space out.
That's a really low price, probaby worth at least $1200 if they are authentic. Maybe even more to the right buyer that absolutely needs them.
Buy em, and try em. If they don't fit, modify the brakes/axles.
I'm gonna call the guy tomorrow and see if i can set something up, i'm just waiting on the buyer for my other saleen rims to get back to me before i can get the cash
