ok after many hours of cussing and thought i finally found the perfect tool to remove the two inner cylinder stud nuts. its a snap on tool, but not an expensive one. snap on offer a line extensions they call wobble plus. these are your basic wobble extension, giving 18* of motion to get into tight spots. a 4inch model of this with a shallow 12mm socket and accompanying ratchet are PERFECT to get those damn things off. no more using a boxend wrench and 30 minutes of your time. cool thing about that extension is that it can be used as a solid model too, depending how far you slide the socket onto the square drive.
im sure someone has already done this. i just wanted to talk about it, lol.
