Bongo Fury

I wanted to replace the right hand rear trim - the seat belt anchorage which had a bracket on to the living unit to keep it upright and steady was undone -- unfortunately trying to fit the replacement trim did not go well and I ended up putting a split in it. Undettered I managed to get the trim fitted - it came to refitting the seat belt anchorage. with the living unit bracket I have tried unsuccessfully to get the bolt to take up any thread. Am I doing something wrong? two of us tried for over an hour with no joy-- I took everything off the bolt just to check it would screw in to confirm the fixing was ok - it went on fine. any suggestions?

Try a different angle of entry

Get the angle right and rotate the bolt anti-clockwise until you feel it click (tricky as its a fine pitch thread) and then gently rotate clockwise to ensure its caught ok.
