Reply to "Shift trunion"

After getting my ZF rebuilt, the shifting was still poor. I ended up replacing my long shift rod (surprisingly crooked) and my triunion bearing (bent like yours). I got a thicker shift rod and larger ID triunion from Pantera Performance. The larger triunion had a thicker mounting stud which should not bend easily. There was no way to drill out the mounting hole without removing the header, so I had to use a die grinder to enlarge the hole in the frame. The new larger nut barely fit into the space below this tab. I ground the hole a bit off center to accomodate the nut.
While you're checking things out, check out your shift shaft as well. If it is bent too, I recommend the thicker shaft and triunion...my car shifts correctly now...but be aware that if you go this route, the new triunion nut is a tight fit. Set the nut below the hole and eyeball the centering. You may have to offset grind the hole as I had to.
