The original springs have a indented pocket the plastic isolators ride in.

Thanks Mike. A picture is definitely worth a thousand words.
Glad you posted as has already mentioned they are replacements.. The yellow stampings have been seen on other models that is what made me thing it was possible that they were originals.. But like ko-lek-tor & Dusk Blue Z posted the spring ends need to look like the ones he posted..
Thanks Darrell.
