Well, I am calling it done. But as I was posting this, I discovered I forget to add the front chin spoiler. So, a little added step besides more dusting of the model. Even though the humidity is fine in the house, and I run a HEPA filter in the hobby room, this model seems to attract dust like a magnet. Anyway, a quick recap of work:
Chassis:
> Corrected to convertible style with center ribbing and chassis plate.
> Fit a Revell 68 Firebird exhaust to fit chassis changes.
> Detailed it out.
Engine:
> Detailed out with wiring and plumbing.
> Revised accessories to add smog and power steering pump in correct placement
> Added smog pump lines to exhaust manifolds.
> Added non-working dipstick in correct location.
Interior:
> Detailed out the interior.
> Added front vents and radio grill on dashboard top (used parts from MCG C1 Corvette PE set)
> Painted Hugger Orange as real car.
> Added seat belt hardware as in the real car.
> Added "wood" trim decals to reflect real car.
> Revised grab handles for realism.
> Crafted front and rear floor mats.
Engine Bay:
> Detailed out.
> Added missing radiator cap (not in kit).
> Added warning stickers on radiator shroud top.
Body:
> Cleaned up and detailed with Model Car Garage PE Set.
> Adjusted setting of front RS grille to reflect real car.
> Opened the grille.
> Using kit decals as templates, created new decals in proper Hugger Orange color.
Wheels and Tires:
> Used AMT Parts Pack Goodyear Polyglas GT White Lettered tires.
> Opened the wheel slots.
> Added valve stems.
> detailed out the wheels.
Here are some photos of the (I thought) finished model (I'll add the spoiler this weekend):
