If that is the case I'm going to check with our local MIdas branch.All based on your recommendation of course. ThanksDonCraig Davis wrote: Quote Selected

We hadbeen running a Swift DB-1 Formula Ford and switched to the DSR Cheetahchassis. I'm no longer actively working on the car, but Bill justreplaced it with a Stohr chassis which is the hot setup right now. It'sgone way high tech compared to when we started and the prices havereally changed....like everything else :-)Take care, Greg Quote Selected

Re: Tail pipe hanger Reply #29 – October 18, 2007, 09:39:34 am Yahoo Message Number: 219 I'm going to see if I can get a forged eye bolt with a collar and that would remove the issue of fatigue and breaking - but even with the current eye bolt that is unlikely since the weight is not very high. I may put in a piece of pipe hanger to prevent up and down movement. The previous hanger was made to flex front to back as the top and bottom were connected by a flexible section. It was that flex that caused the fatigue and brake in the weld. That shouldn't happen with the chain.DonGreg Gimlick wrote: Quote Selected

If you have a marina around you could find a forged eye bolt there.Quoteprevious hanger was made to flex front to back as the top and bottomwere connected by a flexible section.

Mine had the steel strap welded to the frame and then there is apiece of material resembling a chunk of tire between that and the mountaround the pipe. Probably the same as what you had by the looks of thebroken strap still attached to your frame. One of my mounts has a slighttear in the rubber isolator so that will be trouble down the road as itcontinues to move and wear. I'm hoping by the time mine breaks you'llhave the best solution worked out :-)Take care, Greg Quote Selected
