I'm having real trouble understanding what parts to order for the replacement of my front bumper. Even though the truck is a 1992, it's a December 1992 model which I think makes it a 1993 and it appears they changed the bumper in 1993. The underlying support is a round, iron pipe, not the flat, rectangular bar that shows in the picture. I need the underlying support, the chrome center and the two plastic ends. I'd like to just get the whole thing, together, but the parts outlets only seem to sell one component or another, not the whole assembly. I don't want to order a bumper and then have it be for the previous model year because my truck has 1993 attributes. Any suggestions?

my'93 has round pipe under the end caps and it was built in may 93.
