front bumper needs replacing

[lovelandbulldog]

I have a '90 300 sl that over the years of pulling up too close to curbs and the front bumper sitting as close to the ground as it does, there has been alot of damage to it (cracks and breaking) that I need to get it replaced or updated. Any ideas as to where I could find one. How difficult it is to change? Can it be updated? What I understand is that I don't actually need a bumper but a bumper cover? Any input would be appreciated. Thanks
