If they are the same ones listed on ebay the other day I think they ended up selling for $3500.

How hard is it to lay frame on 24's in a NBS Silverado on a 295/35/24?
Not to hard if you know what your doing. You need to tub the firewall and but a new brake booster and also push the a/c back just a little.
