Great, shoot me some pics if you still have my email. One of these days we'll get around to rebuilding the unit in my '67. My son and I are still getting some final touches on the '76 before I get back to the '67.

I have broken 2 differentials with a fastburn crate engine in a 77 vette with a manual and just went through my 3rd with my procharged motor. It seems you can build the IRS up but at a hefty cost. You can retain the handling benefits of the IRS, but a solid axle conversion to a moser m 9 with the autofab kit looks like a good way to go. I think that is what I am going to do since mine is broken. You may not handle as well but you also have less drive train loss
