How does your diff cover look? Any stress cracks? I've seen people blow those up too....
Pics of DSS halfshafts after 126 1/4-mile passes....

I helped him with that, doubleblack, LOL.

Yes, Joe was kind enough to send me his custom-made differential cover brace to use as a template. This is one project that I intend to do now that I'm pulling the diff out again to once again fix leaks. The cover has held up fine so far but I think it's only a matter of time. I'll post pictures when I fab mine up.
BTW, Joe sorry it's been so long. If you need the cover/brace back before any specific time, please let me know. Otherwise, I should be making my brace up within the next few weeks and then I'll send yours back. Thanks again!

Take your time, no hurry. I won't need it anytime soon.

Thanks!

You guys need to start up production on that cover brace. Put me down for one.
What kind of brakes are those? They look sweet.
Brembo sport rotors, Hawk HPS+ pads, stock caliper powdercoated black, and SS speedbleeder. The fronts are the same except for Stoptech SS brake lines and SHM carbon fiber brake duct kit.

MJ, do you have pics of Joe's diff cover? I kinda have a foggy picture of how it looked...how hard is it to mod one up...If I remember correctly, he didn't have to weld anything, correct?
The input shaft looks sweet too...I'm beginning to think it's made different than the one COOP keeps buying for his 99 equiped T56...If I remember correctly, he said he would break his street driving...
Personally, I wouldn't run any of the smaller diameter stronger halfshafts.
Higher grade steels add strength, but the modulus of elasticity does not vary much with the higher grade. What this means is a smaller shaft, while it may be stronger, will be more suseptible to torsional twist. As the halfshaft winds up, it temporarily stores energy, which will be released through the driveline when it untwists. While the halfshaft may not break, because after all it is stronger, the forces may take out something that wasn't beefed up, like the outboard or inboard stub shaft, maybe the center section cover, etc.
Does anyone know what material the stock shafts are? Are they 4340?
Here are data sheets for 4340 and 300M, the modulus of elasticity only changes from 29 to 33.
