As the title suggests, I have made a mould to produce standard style stone tray/valances for the Mighty Boy.
The mould was taken from a new, highly detailed/painted part, and the part itself is made from grey gel coated fibreglass.
I've priced them at $200 (only slightly cheaper than the JDM spoilers I am also making, as they require just as much work to make, and only use a fraction less material) plus postage.
