I went out tonight with every intention of taking them off. Then I had a good look underneath. I'm running mechanical brakes and it looks like all the original brackets are still on. Plus it's now got an electronic fuel pump bolted to the frame. So those aprons cover a lot of hardware. Off or on? If the answer's off, how and how much should I clean up the frame sides? This will never be a show car, just a fun run-around buggy. Thank.
