Whiteline 2 piece Trailing Arm Bushing install

[Ironcheflove]

I was just about to dig into installing a set of Trailing Arm bushings on my 1997 Legacy but I'm ot sure if with the 2 piece split bushing whether they are installed into the old sleeves after burning out the old ones or I've got to cut out/press out the old sleeve and install the new bushings in without a sleeve. The new set only has lube, bushings, and 2 inner sleeves, I've got a funny feeling I'm gonna be pressing/cutting them out the old outer sleeves.
