Just a note, some of the photos in the link are labeled wrong, the driver/ owner of the Budweiser car was Roy Harris not Clayton Harris. Clayton drove Top Fuel cars mostly not Funny Cars
Also, a few of the cars pictured in this album are not Citations. The Harris cars are Omnis and Arrows and the Bob Pickett car is an Arrow.
And, maybe very hard to find but back in the 80's David Peters and David Ostizewski both had large lists of resin funny car bodies including Citation bodies. But, it looks like Chuck has it covered anyway.
