Build some sort of track system with sliders bolted to the floor and attach the box to the track and make some sort of lock to hold it into each position.
What I was hoping was that some of you who have gone to shows & such have seen this done before. Guess I'll be the first!
Winters coming so the box I have will be in the car for the season so I want to keep it simple. That means some "track" type system will be visible.
Possibly a 1"x2" square tube slotted, dovetailed rails or something keyed.
I will look around the shop & see what’s what. I will poke around Home Depot too.
The SQ between where the box is in the pic and when it's moved back to boundary load is significant.
I use my trunk at least twice a week so this project will be worth it.
