Yes, you'll find getting the hard rubber around the link out is the toughest part of the job.
Wouldn't hurt to order yourself some new bolts too.
The back bolt is pressed in from the top and banging on the loosened nut underneath will pop it out.
I took a long drill bit and made some holes in the rubber (don't drill into the frame.
When I took out the bolt ,the bushing fell out.
used a map gas torch (or propane if you have that ) and had to melt the rubber housing. You can use an open pipe wrench and the top knuckle of the wrench will fit into the arm link. Use this to pull on the link as you melt it and the part should come out clean.
When you put the new arm in don't bang on the metal arm to get it into the sleeve. Hit both sides of the rubber housing ,a little bit on each side until it is set in place.
