Awesome

The AC in my 75 280z worked perfectly after years of non-operation, after I managed to replace the pulley and all vacuum hoses... Like clockwork
Though it doesn't look like you need it as much as we do in Southern California on an 80 deg. January day like today

Were it mine, I'd fix the holes, paint it, and leave it alone. If really pressed, I might swap for smaller bumpers and round headlamps of I could find them at all, and if the engine ever let go I'd replace it with an L28e, or turbo.
I like the wheels, is that a vinyl top too? Glad you've kept it around for all these years...
To South Dakota: I always liked your weird, cartoony liscence plates.
