It's a real easy job. The mounts are bushing encased so a pair of sockets, and a "C" clamp are all the is needed.
They will install from either direction as well. I didn't have to heat but I did find a "lok-Tite" type compound on the bushing, and inside the case holes, so a bit of Scotch brite to clear the case holes before install will be helpful. I also used Green Lok-Tite to lube it, and lock it.
I forget but I THINK a 14mm Mac socket fit thru the hole exactly, and a 24mm x 12 point fit the outside.
