Are you talking about how I added pods to a Bonneville HUD?
Bit of fab work, and I'm unsure if the super thin HUD trim panel would support it. But you could always do an add on similar to the ZZP one. Just lay down some cling wrap or something...get the contour of the dash then work from there.
I used a trash bag
Keep in mind, this was my first time glassing and or trying such a thing. Took a lot of time since I learned as I went. Overall though, came out pretty good.
