Unusual Items?

[geunther]

I just bought a 72 Cheyenne Super, short wide. Unrestored and appears completely unmolested. All steel appears original. Only non-factory work that I can find is an older paint job and engine paint.

It has a couple of items on it that I have never seen and was looking for help in identifying.

On the frame in the engine compartment, next to the exhaust manifolds there appears to be some sort of heat shields.

On the back bumper are little rubber steps that look like they were made for this bumper. I have never seen them and they appear to be some sort of dealer installed option.

The question is when I restore the truck do I want to replace these items or leave them off.
