Chrome Bumper Conversion Brackets
These 1/4" CNC plasma-cut steel plates allow you to bolt up a chrome bumper to the rear of a rubbber bumper MGB. Very similar to the bracket included in the $1,295 Moss kit.
Get a used bumper with its hardware and order the corner filler panels from Moss to save a bundle on your conversion.
For a flat fee of $60US, shipped USPS Priorirty Mail in the lower 48, it's not worth it for most of us to make our own.
