The brake drum on the 67 will be different than the earlier pan. The 67 hub had sealed ball bearings where the pan had the star hub with the loose rollers in it. Which means the 67 brake drum had a sealed bearing in it.
The earliest shovels, '66-'68 had the drums on the left side. '69 was the first year for the right side drum.check for left- or right side drum mounting on fork lowers. Early shovels had the drum on the right if I'm not mistaken
Where the hell did you come up with that bullshit!!the early big twin drums are the same as the WLA ones
