What do you call the guys that complain about non stock cars?

and to think I have been having mega guilt feelings because I had to toss the friggin GM buckets that the PO had in my 71 duster project, and then I put in his newly upholstered 68 cuda bench he had. it has NO headrests!!!!!! OK so I admit I used the radio delete plate I had too. so it is a slant car, but I make those V8 sounds with my throat before I crank it....
