I am sure this is dumb but my only experience is cars and bikes. I have a 72 GMC. 1/2 ton. It had no engine so i used a spare 350 I had around. I have never seen motor mounts like these though. the horns from the frame have a single hole in them on the top. my experience has been with a a different style motor mount. are these "clamshell mounts" when I Google mounts I can only find the plate that mounts to the motor. I have that part handled. maybe I don't know the correct name. Anyhow. i need to find the frame horn side of the motor mounts. what are they called, where can i find them.
Thanks
Greg
