Where can I mount the bottle without hitting my tank drilling in?
I'd ideally like to mount it with the valve facing the back of the passenger seat, directly behind the seat on the trunk/sotrage floor on my FRC (basically as far front and right as possible in the trunk area when looking at the car from the rear)

Thanks guys

 

most seem to mount them long ways in the well.

 

1.Get a piece of plywood cut out to the size of your nitrous bottle brackets.
2. pull back the carpet.
3. glue (superglue or another strong adhesive) the plywood to the trunk.
4. put carpet back
5. now you can drill into the plywood to hold your bottle bracket.
Personally I put mine in the center console of the trunk (I have a vert and a remote bottle opener) and I just drilled mine to the trunk. I figured I have to make a hole at the bottom of the tub for my blow down tube a few more holes wont hurt. hope this helps.
