Dean - maybe keep in mind when designing your sheet metal the couple areas that are more prone to wear and damage, like the front end. Your future effort to repair or replace a complex design may help select the final shape.
For your fire system, running the feed lines and nozzles above the bottom of the adjacent frame rail is required per the nhra rulebook. Your nozzle placements look like they’ll do suitable job, all located inside the frame rails.
You’ve probably done this already; suited up with driving shoes/boots on and climbed in/out of the driver’s compartment by yourself to verify the feed lines and nozzles allow unblemished movement. When activated, the fire bottle(s) must completely discharge, not sure of the force, you could test your nozzles with pressurized water to see the spray pattern and adjust as necessary.
When you’re ready to do final feed line and nozzle installations, you might consider a product like this one, or perhaps you already have them or something similar. Alan

Thanks Alan for the input, ive jumped in the seat many times but not with suit yet. i know that will change things but i htink with the nozzles, i think they will be out of the way of knees and feet.
so, i called Good Vibrations today asking about cable for the fire system. The person was extremely helpful and got me to re-think how im setting this up. my plan was to do two seperate systems and pull to activate. In speaking with the sales person, he pointed out NHRA rule and also noted there are half dozen that he knows who have two seperate systems. He mentioned one way to get around it is to hook both cables together if asked about it.
the other thing he brought up is to push and not pull. He mentioned with/when doing the blind-fold test you dont want to be thrashing around trying to find handle to 'pull'. so, since in the front i have it setup to do a pull from bottle end. i would have to do same setup on drivers in so it is a push setup; which he pointed out people do set them up this way.
so, dilemma.. first is getting both handles in one spot that isnt in the way while getting in/out of fed. secondly, building setup to make this a push setup; which is no big deal.. just takes up space. lastly, maybe just set it up so both fire bottles as per rules and not do separate setup..
I understand the premise of having two seperate systems as if one blows you can use your bottle for the other one and save yourself some money not having to fill both bottles. i guess the road block for me is getting both in one spot thats easily accessible and where i can tie both handles together if need be. also, enough room to build the cantilever setup at driver end to make a push setup.
on a side note, i asked how much to refill 10lb bottle. its $130 and recert is $35 per bottle.
