Mine were full of sand mud and gravel but thankfully no rust,while in the process of ordering oil line fitting from Stoddards I checked out their 914 part offerings and found part number 914-559-127-10 described as ''distance washer for rocker panel".
I have fitted them to the panels and was pleased to find there was no more build-up with the exception of a few stones,they are a little hard to fit as they try to full out before you get the bolts started but a good solution and from memory cheap to buy.
Make sure you run a tap into the thread inserts in the body as I found some of mine a bit rusted up,I also found it was better to fit longer bolts .
Thought this maybe some use to others out there.
