when I have raised the shifter on a few A body builds, I use different linkage, pretty much straight rods for the 1-2 / 3-4 and change the reverse linkage to go over the transmission mount.
Sorry to hijack your the Maxcustody but Denny - what Hurst shifter handle # is that? Is it #0015 per chance? I can't make it out in the pic. Also presuming that's a gear vendors tail housing? Thanks!
