Is it possible to change this interior part? The one where people usually mount their A-pillar? If so where can I buy this part from?

Also where can I buy the part on which I have mounted my tweeters? The current one lost a clamp.

TIA

 

Any help appreciated....

 

Yes, you can find replacement a-pillars in the for sale section of this forum. I would assume that our US passenger-side a-pillar would fit your driver-side, but you'll have to check on that. If it does fit, you should be able to get one in perfect condition for about $50.

I don't know about the little triangle piece, but I think I've seen them in the for sale section as well.
