Welcome to the Team Brad!
Bottom color then top if a two tone from memory. Convertible tops have their own trim tag code for color that is a number 1 through 4 once again from memory.
I thought you where going to ask about a V8 versus a L6 as that is a fairly common conflict between trim tag and the VIN. In every case he VIN is the deciding factor. It is the last tag put on the car and reflects how it was actually built. the trim tag was put on the body by Fisher Body when they built the coach (body).
Thanks Dave, I'm in Australia and these old girls are pretty rare over here, they are popular, as are all Chev's as we have an arm of GM here called Holden one of Australia's most loved cars, our big HP cars are about to die with Holden rolling out the last of the big banger's this year (see pic) and Ford doing the same next year, I hope the guys on the forum are cool with helping out as I'm way out of practice, not to mention Ive punched way above my weight with her, what I do know is she is running a 454BB with a Weiand Supercharger brodix heads, two stage fuel system, Turbo400, Custom Tailshaft into a modified 9inch, Cran Cams Hi6 ignition, fireball coil discovering the rest as I go through her.
a few things I need to do to get her 100% are
Fix Power Steering (leaking)
Rewire the hole car its pretty bad, brights flickering, Pro Comp gauges lights not working and general dodgyness with most of the wiring under the dash.
Fuel gauge not working
speedo not working
I didn't buy it for fuel economy but I'm getting 2.3mpg and she stinks of fuel all the time thinking I've got a leak somewhere (priority fix)
the Diffs leaking oil
bolt at bottom of oil pan leaking
and the bolt at the bottom of the left hand front fender (rear one under the car) is missing so it clunks on our crappy roads
All little stuff but I'll be sure to be asking your opinions on fixing some of it, anyway have a great week hope to be talking to you all soon!
