    I intend to do a shackle flip in the near future and have been noodling over how to route the exhaust to accomodate the flip. Obviously, I can't use the stock hanger off of the shackle bracket.

    Any ideas on how should it be done for max clearance?

    Thanks

    Mine cross under the frame behind the stop block and out the side. The pipe makes it's turn before the shackle bracket mount on both trucks so it's closer to the tire. On the 75 the bottom of the fender is cut off so the pipes make a bend up and are clossere to the bed floor. I also have a hanger off one of the bolts that held the metal mud flap/fender suport that is no longer needed. This gives extra suport when you got 10 lb of mud hanging on the pipe. If you plan on trimming up the rear 1/4 now is the time. The 79 doesn't see trail anymore so it just hangs and I haven't had a problem. If you have the factory skid this gets tight on the driverside where the shock is. you may need to notch the skid where it goes vertical in front of the tank to do it this way.

    I don't need no damn shop manual, I got a pornographic memory.

    Thanks Grim,

    That sounds like the way to go. I wasn't prepared to any trimming yet, but absolutely have to get the exhaust done tomorrow. I suppose I'll have to retrofit the tail pipe when the trimming and big tires occur.

    Thanks

    Unless you do it all at once it will have to be done in steps, I cut my rockers off and then had the shocks relocated and the exhaust done at the same time. I have a new exhaust hanger that uses the old upper shock mount and it exits where the old sheet metal used to be.

    Steve,

    Thanks for the response. Hey, are you happy with your shock setup in the new location, it certainly looks functional and is how I intend to do mine, but wasn't too sure of how the geometry worked out. I think I'll do it on the 88 (for practice) while I have the bed out of the thing, sure would make things easier!

    I'll have to do this in stages since I'm running without a muffler and park behind the police station everyday. No way I can get the shocks relocated and 1/4 trimmed tonight and the exhaust guy is putting my Ravin on tomorrow.

    A definite tail pipe retrofit will be required in the future, but for now I'll just keep it out of the way of the shackle.

    Thanks for input,

    John
