Would the Jeep dealership install parts not their own? If not does anyone have some familiarity with Denver/Lakewood area? Who could install it and obtain it by July 14th?
These guys deal in Toyotas mostly but I bet they have many offroad shops and installers connections for all makes so it's worth a shot. They're in Northglenn about 20 min outside Denver. Toyteclifts.com
Oh and I think Northridge4x4 has a location just outside of Denver too. Don't know if the do installs but if not may be able to send you in the right direction.
