Glass Correct.

The ambulance in 'Coltrane vs Duke' was a late-70s (probably 1978) Chevrolet Chevy Van. The one in 'Brotherly Love' was very similar, but the grille and a few minor details were different. I think they may actually have used two different ambulances in 'Brotherly Love' because the one at the hospital has a "63" decal just behind the passenger door, but the one at the end of the chase doesn't. Either way, all I can say for sure is that the ambulances in those two episodes were similar. I'd imagine that the studios (or their vehicle suppliers) had a few of each type of emergency vehicle and added signs to suit whatever show they were in. Dewey's ambulance was completely different being based on a 1979 Ford F-350. BTW. Did anyone notice the blooper with the ambulance in 'Coltrane vs Duke'? Just after Rosco falls out of the ambulance it can be seen making a U-turn in the background, but seconds later when the Dukes turn around the ambulance is back parked on the right.
