Finally got some today and got them fitted fairly easy. Clever too because simple oil service can be done without removing. Then you can take off just front or middle.
Whole set is 3 pieces.
Anyone interested, PM me and i will get back to you with details/cost.
I am also (when I get some of that time stuff),going to make one for fuel tank from HDPE plate - will let you know how well that works.
have put a pic in images.
