The 7 1/4 I have has the 10" drums as well. However, one of the drum hats is different than the other. I don't want to go too crazy with it right now. I'd basically just like to prep it so that I can drive it around for a year or so with little to no problems. After that I'd like to rebuild it with new bearings, bbp axles, disc brakes, and possibly a new pig if I decided I wanted/needed one. It kind of sucks that it seems you have to remove an axle or the pig to change the lubricant. I hear some people drill and tap a hole for ease.
