68 Barracuda Manual Steering Box

I spun the input on mine, it is much harder to spin near the center and gets easier the closer I get to the lock, which i thought was strange. I had my column out at the time so I slid the steering coupler on to make sure it fit, since the last one was a nightmare to install. It was pretty hard to get on all the way, and needed a couple love taps with a mallet. Well, apparently that was a mistake because now I can't get the coupler back off. I guess I'll be leaving it on and assuming the coupler while I install the column. Should make crimping the seal plate on real fun.
