You can go to any local body shop and they can give you the name of who they use for rechrome bumper replacements. You will have to have a good bumper core to give them (the bumper company). If yours is bent they can use it as long as it is not bent really bad.
You may have to check with several places in order to find one that will do it. Most of these places do work for late model vehicles and may not want to do something that old, but I know some will.

The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
