Can you fab? If you can, throw a 7.5 on it and go. If you do bust anything odds are you are handy enough to fix it. I run a 7.5 3 spring meyers on my 2004 QC 1500 SLT and it handles it like a champ after a few cranks of the torsion bars and bilstein shocks.
If you can't fab, may be check with snow way, they have real light plows that may bolt on to your specific model
