1964 273 valve covers

[64dreamer]

I am wanting to replace my stock valve covers with some mopar performance covers, however when I check applications they show 1966 thru 1970s. When I check other brands I find 1964 thru 1970s sb mopars are all the same part number. My question is was 1964 273 valve covers different or will all sb mopars valve covers fit

do y ou have the breathers and pvc and the wire clips including inserts I would trade you some mopar performance for unleaking oem 66 or 65-67 273 valve covers they will have to look like oem but my mopar performance do color doesn't matter no dents or dings or deep scratches
