Hi, everyone, here's the layout on the car. We all agree, a 454 wasn't availible in 1975, 1974 was the last year. What they have told me, is that Nickey Chevrolet built and installed this 454 in it. The window sticker is broken down as follow:
A31 Power Windows
C07 Auxiliary Hardtop
C60 Four-season Air Conditioning
FE7 Gymkhana Suspenion
J50 Power Brakes
L48 350-4 BBL V-8 Engine
N37 Tilt-Telescopic Steering Wheel
N41 Power Steering
QRZ GR70-15/B STL Belted Radial W/L
UA1 Heavy Duty Battery
U69 AM/FM Radio
19R Folding Convertible Top Black
192 LBB2 Black Custom Interior

They're trying to get the original owner to reply to there Phone calls. Hope this helps, and I guess it would be like any other NICKEY, your call.
