[MO Olds]

Hi - I searched some threads here and several parts store websites (NAPA, AZ, etc.) trying to find the A/C hose for a 403. I know there are new specialty manufacturers making them but wanted to see if I can find it locally first; also hoping not to have to pay $250-300 for a hose. Anyone have an original GM Delco part number to cross reference? None of the part stores websites return results by make/model.

I did find one comparable in an actual book catalog that looks like the original although does not show its fits the 79 Olds 403 configuration; I think its for the R4 pancake compressor but looks like it might work. Picture below. Thanks in advance!
