There are 2 of those trucks in a junkyard about an hr. from me & I think they both have rear bumpers. Do you have a picture as to what it looks like? My email tinhuntr@sbcglobal.net
I have one that is still attached to the truck, but not sure if it is the correct one. I could email a pic if you email me at bdziewior@yahoo.com. I am in Wisconsin
