"I am very happy with the Drive Shaft, it installed relatively easy and I appreciate the extra detail on the finish cut on the exterior of the Drive Shaft. Performance wise their is a definate improvement in throttle response, no vibration, in fact, I believe it reduced noise. I drove 90 miles today and gas mileage improved by about 1 mile per gallon."

"Thanks for the direct bolt driveshaft. We installed in my Bullitt. I think everyone involved was impressed with the whole package…quality of DS, the installation kit you included and how easy it was to install. The installer also runs a web blog and took some pictures and planning to run a story. That won’t hurt your publicity at all.

Question – one of the main reasons I made the switch was to eliminate the “clunk”. It accomplished doing that about 90% but there is still some noise. I can’t figure out where it could be coming from. I’m assuming it’s still somewhere between the driveshaft and rear differential but I just don’t see how that’s possible unless it’s connected with the pinion flange somehow. From a mechanical engineering standpoint, there is nothing that is not solidly bolted in there. Any ideas? Would it have been eliminated if I had gone with a new adapter plate or pinion flange? Thanks for your comments. Glenn"

Glenn, We can't see where an adapter plate or pinion flange style shaft would be any better (maybe worse). -David
