You will be amazed at how much tension the stock bushings have on them. After I got everthing released the tension actually rotated the arm up on it own. Also I used the 10 ton cylinder on the press and that was enough to get er done...it did sound like it was close to be maxed on a couple of pushes.
Mark the rear compression bearing keeper for the correct orientation and mind the 7/16 distance outlined in the included instructions. A 32 mm socket fit just right if you need to drift that bearing in a little to get the holes to line up. I had one that was perfect and one that I had to adjust about a 1/16.
if you have any questions let me know and I'll help if I can.
