Slant six on boost - upgrade the driveshaft?

For years I ran Driveshafts out of 70's AMC Station Wagons with 904
Transmissions. Only 2 1/2 and 10 1/2 / 11 Pounds. Also a yoke that
is way shorter and lighter than the Mopar parts.

That = I did explode @ 510 HP. in my E/SA Demon. I may have got a defective one?
It put 6 large holes in the floorboards and the trans broke in two completely
right at front pump and it made a real big mess.

Actually lighter than the Aluminum shaft in the Superstock today.

It happened at Woodburn Or. in the lights and a piece came within an inch of my
opponents Windshield.

I do not run them anymore!
