The r40 clutch shouldnt blow up? Just run the weights without the spring. I did anyhow as the spring was funky.

Woohoo there is some posting action in the R40 thread 
Rear end of the car is almost done and it has been a pleasure to work on thus far. Can't believe how easy the diff and the 2 speed shaft dropped into the bulkhead compared to the S720
This car is going to be nice to work on, much like my belovered shaft drive cars...

S9550 all around. Lighter weight and almost as fast and powerful as the 9451.
