Jounce Stop Bumper ?

You might have to resize your pic. If it is too large the system simply will not load it. Get your 16 y.o. daughter to help you resize if necessary and post the pic.

Also, tell us what you are working on. It sounds way to big for the front end. The rear diff bumper on my car was a push into a bracket style. There are some smaller ones that attach to the rear frame rail over the rear axle, but I think they are much smaller than the dimension you gave also.
