Hi Jim,

Been there. First remove rear wheels and re-install 180 degrees out. The holes in the Alcoa are too small for both stems.

While the wheels are off, remove the plastic extender on the inside steel and cap off the outside Alcoa wheel. Install a fill thru cap. Any large truck tire shop will probably either have them in the shop or under the counter. They look like this.

The straight on air gauge will do the inside and the angle will fit the Alcoa wheels. I put caps on all 6 stems.
