Helluva friend, helluva friend indeed. I'm thinking of a kind "gift" for his efforts...
I did have to leave behind an RB8 and a 176 from the haul location but I may have access to those yet...
The 174 bracket looks to be fabbed. The beacon was mounted on the front of an old step-van used for an equipment truck, back in the day. It had to be mounted below the roofline to clear the old firehouse door so it was mounted above the split windshield on this bracket. Unfortunately also, because of the height issue, the skirt is cut short.
A Mars crossbar would be ideal for those Skybolts as I was also given another blue lens. Oh, the wheels are turning, be sure of that... That and a pair of Mars can lights... maybe an 888 for the middle?
