The Monogram one with the red car is an 1983 I think. If you are looking for 84.5 GT350 decals they are out there, try ebay. There is a member here that makes them.
For those of you who have the Pace 24" spray booth where are you getting your 12 x 24 filters? Seems to me that the 12x24 size is almost obsolete? Might start using the 14x24 since they are way more available.
