I'm getting ready to do an engine swap in my Pantera and have everything loose but the speedo cable. I undid the knurled nut but the cable wouldn't release. The large nut on the other side of the cross gear (on ZF case) is loose but I didn't pull it there. I thought I remembered reading a POCA article about the possibility of the cross gear falling into the case. Shouldn't the cable release at the knurled nut, leaving the cross gear housing attached to the ZF? Please advise.
