Boss,

Your angle (~18 degrees) is on the limit of some flanges, so I would check for interference between the adjacent parts. The high angle decreases the joint rating somewhat, but I don't think it will be a problem. Just in case, I would use a driveshaft strap or equivalent to deep a broken u-joint from breaking one of your body's joints...

Because there'll be quite a bit of extra heat generated, keep a close eye on the joint lubrication. Initiallly, I'd check it every 1000 miles. If it doesn't look like you're throwing a lot of grease, you can increase the paranoia interval.
