Thank you
Thanks for all of the replies and suggestions.  All will be taken into consideration.
I apologize for sounding so bitter.  I’m really not like this.  I guess I’m more frustrated than bitter.  I love my ambulance and I’m proud to show it off but I get very discouraged with all of the idiots who yell out “GHOSTBUSTERS”.  My ’75 does not look like the movie car!  The other day, I was in contact with a very knowledgeable medical rep because I am looking for a circa 1975 Bird Mark 7 respirator.  He knew all about what would be appropriate for my 1975.  When I sent him a photo of my ’75 Superior XL, he replied “Cool, Ghostbusters!”  UGH!
