Coupler Cover ?
ss4:
that was my thought as well more of a guard than a safety shield. I would bet 1/2" would be the sfi requirement.
dreracecar:
For all cars with driveshafts that do not contain universal joints but pass any part of the driver’s
body: Each end of driveshaft must have a full 360-degree cover of minimum 1/16-inch steel or
1/8-inch aluminum. Rear cover must surround the coupler. Front cover must surround the
driveshaft from the back of the reverser to the end of the splicer sleeve in the area of the
driver’s legs. All covers must be securely mounted to frame, suitable crossmember, reverser, or
third member.
I dont think that Dzus buttons qualify as "securely" but your tech guy might think differently.
I prefer covering the coupler as close as I can with round tubing. hard to tell from the pic but its a .125 wall DOM steel tube bolted to 3rd member

So you took T6 aluminum and changed it to "O" (dead soft)condition. Would have been better to have bent the "U" and bolted angle to it in order to keep the T6 heat treat
PSweeney:
thats cool, I like that, I have my anti-rotation plate bolted to the pinion support too. The spacers you have standing it off the radiused portion of the pinion support would work out well, so too would using the studs over bolts.
Have you by chance got a picture of the other end of your shifter please ? I'm interested to see how you locate and operate the other end ?. I'm doing the same but I've inverted the ratchet shifter and hung it from the steering crossbars up out the way of my feet. I have links going back to a guide plate on the center section. I couldn't think of a cleaner solution which would allow the rod to articulate and still slide through it.

Just at the 90. I wouldn't call it dead soft. I looked at using 1" aluminum angle but by the time it was welded the strength would be the same. So is there a definition of "securely" or just someone subjective opinion.
