Im trying to figure out if a LR4 interior passenger a-pillar/post trim will fit my LR3. I broke it fixing the stupid drain as I couldn't get the bolt out even with using the correct t 27.

A Post Upper L319 right

Stripped bolt

 

Pretty sure it's actually a T30. I remember seeing T27 somewhere as well but a T30 fit mine and, well, that's probably a better idea.

Are you looking for the bolt or the full trim piece? Can't see any trouble with your trim and I would think a bolt from your stash or the local hardware store that matched would be OK. I think mine had some loctite on it.

 

The trim piece. I had to break it off the bolt to get to the bolt for removal.

 

 

My advice would be to look up the part on a dealer parts site and/or ebay used parts listings.

If the part # is the same for both vehicles, there's your answer. I can't speak to it myself whether they're interchangeable or not though....
