I made the water temperature probe/sender and the bellhousing bolts & washers. I also made decals for the "fan" belts and fuel lines.
I made the worm type hose clamps for the radiator hoses that connect to the engine. I also made decals for the hoses. The lower (water pump) hose is actually an upper hose for a small block C3 Corvette, and the upper is a big block C3 hose. That's just the way they fit in this application. (The lettering is intentionally distressed as the printing the real ones is often that way.)
