Use your press to center everything,
and install your retainer clips
don't be afraid to drive the clips in with a small punch if you have to..
and if you really can't get them to go, make sure you didn't drop a needle bearing in the a cap or smush a groove closed with the press..
better to find it now and down the truck for a day or two waiting for parts, than scab it on and have it blow apart on the road, leaving you waiting for AAA and down two days waiting for parts..
