I have two 914 73-74 chrome front bumpers for sale. I do not know the history on them, as I received them from my dad. But I believe they were removed to do a bumper conversion on an early car.
The first (Bumper #1) is very excellent condition and the chrome looks like it has not seen much road use. Asking price is $425 plus shipping.
The second (Bumper #2) is very nice condition and a very small (almost) unnoticeable dent that would be covered by the top rubber cover. Also, the dent could easily be knocked out with a rubber mallet. The bumper has one other very small dent on the front. The back has some very minor surface rust that could be cured with sanding paper and spray paint for protection. **SOLD**
