Well Vaughn, you must be a good Scotsman since you spell your last name with "Mac" instead of the dreaded "Mc".
I work 14/14 as a Paramedic offshore and when I'm home I usually on call with my Rural Fire District as a First Responder, meaning the only ambulance is usually 25-30 minutes away and I can get there quicker and start treatment. I use my truck as a Fast Response Vehicle. The strobes will be used as warning devices while I am enroute and also to warn motorists of a possible accident. I already have stobes mounted under the rearview mirror.
Well, after having some more coffee this afternoon to re-energize the braincells, I went and took another look and found the 3 bolts that hoid the assembly. Probably start the drilling process tommorrow. BTW, the panel that controls the strobes is about 3"x 1 3/4". It has two rocker switches and a rotary knob to control the flash patterns. I flush mounted it in the sunglass holder door on the overhead console. Hopefully I'll get some pics uploaded after the install is finished.
