Looking great. I am confused on the heater hose bracket question. They look correct to me. Here is my set up and my goal was it to look factory. Sorry I thought it would show more detail for some reason I only have a low resolution photo showing the hose brackets, but they look the same and I kept the bare metal unpainted and shot them with clear.
Sorry I was so focused on the brackets that I didn't even see the A/C set up. I am sick and need more coffee. Don't think I have been much help just confusing the situation.
When trying to return my engine bay to the way the factory did it, this is the way my 67 383-2 w/a.c. Is supposed to be from the research I did and with the help of other members here.
I suppose that the A/C cars have the longer "hourglass" straps, to locate the hoses away from the A/C line compressor muffler - and non A/C cars have the shorter "oval" strap
