Finding Where To Drill Into a Smooth Inside Wall

[SlavetotheViking]

Hi all,

I'm wanting to fit L-track (aka airline rails, captive track, cargo track, etc.) along the inside of my recently acquired LWB combi's load bay walls.

I did plenty of rummaging around and home-made modding of my old T4, inside and out, so I'm happy enough to get my hands dirty. The issue is that the load bay has been carpeted, very nicely, floor to ceiling, with no obvious indication of what lies beneath – I can't see what's structural beams and what's just space covered by cards and fabric. I don't want to mistakenly rivnut into hardboard...

Any sensible ways for finding something I can securely drill into?

Interesting point...

Yeah, that could be worth a try!

Here's what the side of my LWB looks like with the panels removed. Might help you with a place to start

Cool, ta. As I thought, just taking a line back from the rail below the sliding door's windows puts me in the right place.
