My Z has had a hole in the vinyl in the area of the throttle slot for years...too many years to remember!!

The attached pictures show a simple fix: Find a piece of plastic with a surface textured similar to the surrounding vinyl, cut it to fit, place it and colour it to match. In this case, the plastic is from the lid of a bottle of almonds.

Much more economical repair than sourcing one. Those covers have fetched some serious cash lately from what i've seen.

I love that repair, nice looking and creative!
