[66K20]

I need to replace the hard fuel line between the fuel pump and carb on my '66 K20 with 292. Does a prebent hard line exist for this truck? I have found several 250 hard lines but none for the 292, unless I look into the 67-72 era trucks. Are there any external differences in the 67-72 292 compared to a '66 292?

Thanks!
