Well, my feeble brain gave up on the whole leaf suspension thing after I went thru the whole power steering, parabolic, shackle, pinion angle, merry go round. That's why there's a Designa going under the 2A. Too much home brew reengineering for my taste. And my booger welds and grinding didn't make any of the schmidt any prettier that's for sure. My extended track rod was reedonkulous.
I applaud the OP for going on with the 24 splines. I'm sure it works fine, and he seems happy with it.
