"Probably explains why I only see them on high end vehicles ... ????"
- yes, like on my 18 year old Toyota Tiger that cost 605,000 baht new. ????
I went to the Chai Autosound place in your link, on the 4024 in Ratsada.
They spent about 45 minutes moving loads of old bull bars, nudge bars, roof racks, etc, that they had stored at the very back. The woman staff person was sure they had one like my old one and when they eventually found it, it didn't fit! It was too wide.
So she ordered one for me. 6,000 baht.
