need help identifying and locating part
 

These tabs came with my 1980 30' Velocity I'm restoring.
I have everything except one mounting plate for one of the planes.
I would like to be able to find this one part instead of replacing the whole system.
I havent had any luck finding a match I'm hoping someone will recognize these and help me locate a match.
Thanks for any help

They look like regular Keikafer trim tab backing plates with waht looks like a 380 tab cut off half way. For a better look I would just use new or like new 280 plates. Ebay sometimes and sometimes on here in the swap shop section you can find these.

They look like regular K-planes to me also and look like the standard 280/380 backing plate.
