Lower rad hose for 69 GMC (305?)

[Jarvis-69 GMC 1500CK]

Got a 69 GMC 1500 2WD it came with the 307 (I think it was) has since had a 305 put in ( not my doing ) the lower rad hose is kinked and obviously wrong, I know this is a "none standard" option for this truck and I am having issues finding he "right" part.

My question is what should I ask for at the part stores/does anyone make a rad hose for my particular combination/does someone have something that has worked for them with a 305? The engine appears to be from a mid/late 70's vehicle (Has a bunch of plugged vacuum lines that went to emissions equipment and the oil filter it uses also indicates this)
