!973 2.0 questions - Paint and configuration, Need some information please Options

[Downerman]

So I picked this up in Van Nuys and it's down to just the shell. Doors, hoods, well everything off the car. Rust cut out and repaired and next week the dustless blaster get's here and then I epoxy primer the car.

Now, that being said, the original color is L-80E which is Ivory White. I have read ALL of the threads and no one actually has the new paint formula to share here in the forums. My paint supplier told me to bring in some paint off the car. that's impossible as it sits 3' off the ground and ready to strip. I've been told to buy a quality paint (learned that lesson with my last car) and was told to get Matrix because PPG does not make a two stage that matches that L-80E number. Is there anyone who has sprayed a newer paint that feels the shade matches the original Ivory White? If so can you recommend the brand and formula?

Second thing is my car has the black undercoat along the underside but behind the rockers is white. I assume that the car was originally completely painted white as I see it under the black coating. I was planning on hitting some spots with some clear POR15, let dry of course, then entire car with PPG DP50LF with 401 Catalyst, then sealing all the seams with Wurth Seam Sealer GR1019. Then hit the underside with Raptor bed liner (Black) as many here have good things to say about it.
Any flaws or experience here from you guys that can share your experiences?

So my 73 is after the serial number denoting the black sills meaning I should have the black and mine are aluminum. I got two window/trim sets with the deal. One is polished Aluminum and the other is polished aluminum that has been either painted black or anodized black??? Is the black one correct? I can't imagine they would just paint those sills as they take some serious abuse but what did they use? The glove box lock was also painted black and that seems weird to me. I soaked it in brake fluid and it's of course chrome and looking good but was it black as well? It has the original center console with the correct gauges and I recently purchased a correct 150 silver dot speedo for the car. Are there any other 73 2.0 secrets that I might be missing?

On a side note, I called Porsche in Atlanta and they took my vin and engine/trans numbers and the car is numbers matching. The engine and trans are out of the car and appear to be complete. No compression out of #3 (Figures right?). If memory serves me, do the valves sometimes get stuck? This engine has sat for years and years. I guess it really doesn't matter because I'm planning on new rings and some head work (minimum). It will go to the machine shop for some thorough measurements.

Oh yeah, can you get a repo door sticker that has the vin in dot matrix form? Mine is ok but I'm not sure how to protect it from the blaster other than have him not get near it.

Thanks for reading.
