AS I prepare the rear IRS parts for installation, the rear toe link is giving me fits. I know this should be a simple installation but the helm joint is not cooperating to get the jam nut on it supplied by FFR. I have tried getting this jam nut to thread on the hem joint barrel, but the threads seemed mismatched or out of whack.. I cannot see any thing wrong with the him joint threads as I can screw it down onto the barrel. See picture below. It is both nuts, so I think I must be doing something wrong here. Any advice?

Here is the picture.

Thanks in advance for the help.
