Kindof irresponsible the way some of this repop stuff is marketed .. "OEM Style" whatever that means.

The '68 service manual shows the same as your '69 parts book. Granted they sometimes continued to use older photos in the books but I think the band style spring clamps shown in the books are correct. The crimped band clamps are for items not requiring regular service.
