Here's my update.

I liken this to making a cake, you need a lot of different ingredients for it to come our right. I took a advice from the helpers here and went forward.

The firewall is installed and I can't make it any better, second time around helps too. After setting the firewall and tacking it in with some ca, using a 2 mm spacer behind the spinner backplate I realized this was TOO much of a gap. Tore it out and used a 1.1 mm spacer, much better. 32Ford set me straight here!

On to the cooling vents.
Not much to report other than trying to find the center-line of the nose ring. I layed out the tape lines on fuse where I would trace the template with a marker pen. Used a Dremel with a cut-off wheel to do the rough cut, filed and hand sanded the rest.

No matter how much time I spent on the layout It still didn't come out as symmetrical as I would have liked. It's close but needs some TLC.
