Can't get the poly bushing into my rear control arm.

[ChuckLee]

So I easily removed the old worn rubber bushing from the rear control arms by drilling holes into the rubber bushings.

i went to install the new poly bushing from LMC by putting the special lube on it all, then I put the collar in the bushing and started pressing it into the arm with a C clamp. Now it's 3/4 way in, and I cannot get it the rest of the way in, and have no idea how I would get it out. Lol. No, I didn't freeze the bushings first, but I did remember reading that in the forum, unfortunately I remembered that once the bushing got stuck. Any suggestions?

It is pushed in enough that I was able to insert the trail arm bolt through the collar and some big washers and a LOT of air with the impact gun. Now it's stuck.

I wonder if freezing the remaining part of the bushing with some dry ice would help it go in?
