| | ====== 1958-1969 XLCH Primary Covers ====== |
| | The XLCH primary "tin" cover has several versions. Below are the two used on production models from 1958-1969. ((Moon Wolf of the XLFORUM http://xlforum.net/forums/showthread.php?t=1062720)) \\ |
| | There are no casting numbers on these covers as they are stamped steel. \\ |
| | The 1958-1963 version is very similar to the 1964-1969 version. The only difference can be seen from the back. \\ |
| | Notice that the inside of the derby on the 1958-1963 version is smooth because of the two-piece construction. \\ |
| | The '58-'63 XLCH primary covers are sometimes referred to as "double derbies". \\ |
