I put my new tranny mount and my old tranny mount side by side when i was swapping them out.
This is what they looked like.
Its the Crown Automotive 52002334.
Also, have you heard of hydrodipping. Ive had some motorcycle parts hydrodipped in carbon fibre. Its an amazing finish. They can do anything in any type of pattern. It comes up hard wearing and glossy. If you give them a few of your trims, they can match everything up.
I used
https://www.hydrowizards.com.au/ and they are in Brisbane.
