Instead of just storing your removed interior for maybe putting it back at a later date i would happily look after it for you
Much better then it getting damp and unloved in a garage somewhere

To remain on topic, just got for it, you only live once might aswell enjoy it. If you go bolt in cage and remove the components then theres nothing to stop you going back in the future

Ah, there is a problem with the bolt in cage, and that's where the bottom of the cage mounts to. There are plates that need to be welded to the sills, with holes drilled into the sill to allow the nut on the other side of the plate to sit inside, allow the top of the plate to sit flush with the sill.



As you can see, they don't sit that flush. I cant remember if that with with the nuts there or not

Yes i thought that would be the case with the cages. Its the same with the ones that we fit at my work.
Still in theory should be easy enough to hide them after though shouldnt it? With ours if the car no longer needs a cage after a period of testing we just patch the holes and flat them back and grind the plates off. I admit not particularly nice but im sure it could be done with more finesse if required.
