Cascadia - Help with removal….

I’m definitely no expert but I would start by removing the headliner if it can be done. Maybe gain access to cut them off from inside the cab.

The real question is what to do about the holes left behind..

 

You’re going to have to pull your headliner out of the cab. Once they’re gone you’ll have to put some short button head bolts in the holes. You’ll have to weather proof the bolts and holes to the best of your ability.

That said, if your roof isn’t currently leaking when it rains I’d probably just leave them alone.

 

Cut the brackets off flush with roof. Angle grinder and cut off wheel.

Leave the bolts and rest of brackets / plates on the roof.
