REAR
Rear Bumper Conversion Brackets (Pair) Early Blade Bumper on Later Europa Bumper Models.
These conversion brackets bolt directly onto 68-73 Standard Beetles and exit out of the stock fender/bracket hole.
Due to their size and design, being made to an early bracket dimension at the fender, they allow you to install early fenders on your car at the same time if you wish.

Mounting holes are slotted to accommodate most manufacturer's bumpers.
