I have the old bump stop off of the truck. Its a 87 4x4 This is the front lower one I am talking about. They are triangle shaped and mount with a strap. The casting number on it is 4322534.
The upper one is cone shaped and I can find that one. Its just this lower one that I cant seem to find.
Any suggestions would be appreciated.

PS. if needed I can post a picture of it.
