LCA Bushing install question

Brand new to the site and I gotta say everyone has been a ton of help. I'm working on the front end of my 07 taco and I'm replacing the UCA and LCA bushings, amongst other things. My question is as I've tried to understand the correct way to press in the LCA bushings, it states in the website I've been using that I have to line up the "bush protrusions" that are supposed to be on the bushing itself. On the rear bushing there are rubber protrusions, but on the forward one there is none. The online repair manual is for an 05 and 06 but I'm just taking a wild stab that its the same as the 07. Is the alignment as critical for the front as it is the back as far as the camber and caster is concerned? Do you think I have the wrong bushings? I just dont want to press in some bushings to have them be installed wrong and then have to rip it all back out to move the bushings around. Any advice would be appreciated. Heres the website I've been using
