I test fit a M1009 rear bumper. The frame horn holes don't match up, but that is just a matter of marking and drilling new ones. However, the already pretty weak M1009 pintle would be even weaker on a suburban without a lot of work.
A m1008 bumper is even harder to fit. But, the stronger bumper to start with, a step, no interference with the receiver hitch, a place to sit or set stuff and different look make we want to try it. There have been several post about how people made them fit. I am going to do a detailed thread about how I worked it once I am done actually doing it. I also envision a swing away spare tire mount in the future and the step bumper to me is a better platform to do that with.
I got the rest of the truck painted this morning. It looks like I got done just in time. We got rain coming the next few days. Now I just need to put it all back together again. Along with the valence,hood and fenders still to be prepped and painted. But until the engine is in and all set up. I really don't want to put the front body on or have it sitting around being a scratch magnet.
