Got the Old Girl all back together today. Took a couple pics of the rear end braces and the trans and engine filters after I cut them open for inspection. All good inside, I'm a happy camper. Took it out for a test spin to see just how much more rigid it is with the brace, WOW talk about stiff. Had one front wheel about 6" in the air and couldn't notice any frame twist.
All I'm gonna say on the brace issue is if your running an aluminum case Super or a GT and you don't have it braced you will wish you did when you crack it, end of sermon.
