Among the parts I received with the 65 I'm restoring are two coil spring covers. Back in 1971, when I was installing grease fittings in my 66 GT, I'm positive there weren't any spring covers. They must have been removed by the previous owner or a mechanic sometime. Mine need cleaning up and painting. Do these serve a real pupose? Are they structural or do they offer protection. I'll put them on, but my old car seemed fine without them.
