How to compress MM1 angling ram pistons?

    Heres my issue,

    Ive got a MM1 9' plow setup that I removed the blade from to swap on an 8' MM1 blade (the 9' is too big for around here) they appear to be completely interchangeable with each other.

    I got the 8' blade all lined up and it seems like the angling rams need to be compressed in several inches to allow me to insert the center pin. Is there any particular way I should do this?

    I already tried fastening the 2 ram pins and pushing the plow up against a snowbank with no success.

    Any advice?

    Thanks in advance, just trying to get this rig ready before the next storm up here.

    How about cracking a hose loose and letting a little fluid out?

    Or plug it in to the truck and push on the left cylinder while someone bumps the controller to the left. One you get one side retracted, you should be able to get the center bolt through. Then you can angle it around, using the controller, to get the other side attached.
