Ok, a little cooler out there today -- about 10 degrees. Kicked on the furnace in the garage and can live with 55 degrees.
I had to change out the 14 bolt srw lugs which were 2 3/4" long. Put in dually lugs which are about 3 1/2" long. Only needed a 1/4" for a full lug nut but got a half inch extra.
Windshield, header, wiper, and one piece headliner is in... I do not want to talk about the headliner.
On duallies, inside measurement from sidewalls is 49 inches. Tires are 7.50x16's.
