Here’s what I discovered, thanks to Brent’s tickling my thoughts. I thought that the bolts weren’t long enough to go through the base built into the cabin top.
The base that is built into the cabin top is apparently not solid. I removed the wood trim under the hatch, peeled back the headliner, and found what appears to be a ceiling made of particle board. There are no through bolts showing underneath.
Now it looks as though I’ll have to remove the headliner and particle board ceiling to access the nuts on the bottom of the bolts.
Ugh! Please tell me there’s an easier way!
