I'm sorry to be the one to tell you, but this car does break some of the 10 commandments as described in the bible (old and new testament)
I wouldn't want to put it in a category, but lucky for me you already did in signwriting. It's a combination of vin+age and hoodride! Take my advice and start by putting it a slight bit higher at the back, keep the empi 8 (odd on an oval, but was done before with a lot of succes). Definitely loose the aerial (if not at least the rat fink on top), the sun visor and the eyebrows on the headlights. I know you like Jussi's car so keep the engine as it is: wild and unclean
You'll be one step closer to cal- look!
