Battery Disconnect Switch

Which switch do you guys like better (see links)?  I'm getting ready to install a NHRA-required (only required if battery has been re-located from stock position) remote battery disconnect switch on the back of my car.  I want to locate it next to the license plate.  Problem: due to the tail light surround, that is a double panel!

 

I need a long switch stud type switch to get thru the double panel, and there aren't many options.  So, which switch do you guys like better?

I know I could do a remote T-handle push-pull switch, but I just don't want to have the hole in the back of the car sucking fumes (I still drive this thing on the street).  The Flaming River switch isn't really a long-stud, but I think I could use the length of the T-handle to effectively make it function like a long-stud.  Any thoughts from the smart guys?

I've been working on a similar project for my engine kill switch; It's not finished (Needs more grinding and powder coat), but it's getting there!

 

Basically I took a sink drain from Home Depot, cut the bottom off, welded a washer over the hole, through which I'll connect the T-handle. The drain being threaded makes it very simple to mount with the large supplied nut, and a rubber gasket should seal it well enough should I ever get caught in some rain. The eventual plan is to replace the quarter windows with Lexan (I've got a 2+2, so they are a little larger) and cut a hole to mount this in:

Edit: I'm still waiting for that PM with pictures of that fender-exit exhaust by the way! :)

Damn, that is COOL!  But you are gonna have to put a huge hole in the car, aren't you? 

 

The fender exhaust is way down on my list-I won't forget you, but it will be late this winter before it is done.  Priorities for the winter are: stopping, NHRA certification, fun stuff.  The exhaust cut outs are in the fun stuff category.

Big hole, yes. However, since I plan to mount it in the quarter window I'm able to avoid any extra body work, and I can easily swap in a stock piece later on, should I ever be so inclined.

 

Another thing to consider is that mounting any switch that makes you unable to restart the car without exiting the vehicle could be disastrous should you ever find yourself in an accident that requires you to get out of the way in a hurry. I'm pretty sure there was an incident like that a while back where the driver had a minor collision, came to stop on the course and had the track worker immediately run up and kill it. Unfortunately he could only watch the track worker clear out of the way as another car came around the corner with no chance of avoidance. The car potentially could have made it off the course if only he could start it up again!

 

Pretty sure one of the sanctioning bodies amended the rules to say the driver had to be able to reset any and all kill switches while still in harness...
