I have a recently purchased ‘68 GS-400 convertible that didn’t come with a boot, so I’m looking into buying an after market one. One style (early) notes that there are plastic clips sewn into the boot that slide under the chrome trim. The 2nd style uses individual stainless clips that I need to purchase separately. How do I tell which style my car needs, or will either one work? Thanks in advance to all for your help!
