I second Desert Rat for suspension installation. When I got my Eibach, they were going to install it for the best price I could find anywhere, and sounded like they actually knew what they were talking about. I didn't end up using them, due to it being at the beginning of all the pandemic issues last March and did it myself, but would have been glad to have them do it. I'm not sure where they are on slider/bumper installs, but they would be a good place to check - their labor rates are way more reasonable than anyone else I checked with. You might also contact Accessories Unlimited in Abq. I don't know much about them, but I know they sell bumpers and such, so they must install them...
