Shortly after I posted the last updates in November I started to get a vibration under deceleration. My custom driveshaft was the culprit. Since the front shaft has a slip joint at both ends I was unable to have it balanced. I came across an adapter plate I thought would allow me to bolt up a spicer 1310 yoke to the rear differential. But, things are never that simple. The adapter I bought had the wrong bolt hole circles diameters(older Mercedes). Luckily, Mike at JTR was able to machine and tap the 100mm bolt hole circle to the adapter. So now after a few weeks of waiting I finally have the adapter bolted up. Now I can order a balanced 1 piece driveshaft. The Megasquirt is on hold at the moment.
The drive-shaft dampener apparently can't handle the hard shifting and power. This is my cracked dampener/coupler with 38k miles. Only about 150 miles with the swap.
