Re: allignment help
Judging by your description, your still out of alignment. It should never take the force of 2 people to get it to slide in. I played with mine many hours up and down before I got it right. It should slide in easily at every 1/4 turn of the crank. If it goes in easily at TDC and then you turn it 90 or 180 degrees and it gets tighter you are still off. Also as Don said if one of your rear mounts has sagged you will never get it right. This was my case, sat for 2 years, mount sagged and coupler took a set that way. Had to change mounts and coupler to get it right. If it's not as close to dead on as you can get it, it wont last very long. The coupler that is. Keep trying, you will get it.
