I bought the CVA alarm and the separate mounting kit for odd numbered lug nut count. The separate kit is nothing more than a mounting plate with pre-drilled holes for all the different patterns. I had to make my own lug nut brackets because of the large size.
The three blanks cut from 1/8" steel.
Drilling the 1/4" mounting holes and 3/4" pilot hole for the punch.
Holes drilled ready for 1-1/8" punch
Punching the 1-1/8" lug nut holes.
Takes a torque wrench.
Cleaning up the punched holes.
Checking lug nut fit.
Lug nut holes punched.
Bending the bracket using a drill bit to get the curvature.

All three done.

Painting brackets and bell. I preferred the bell painted.

Reminds me of a train coming in...
