Oil line part numbers for backdate?
 

I'm putting headers on my '78 and it's my understanding I'll need to swap out some oil lines.

There's plenty of threads on it here but none of them list the part numbers of what I need to order.

There seems to be a bunch of them and I want to make sure I get the right ones. Thanks!

Aftermarket ones are available. Fair warning, none of them are going to fit right without a lot of heat, bending, grunting and swearing.

There's a chance your stock oil lines will fit depending on the new header design.

I was told that the headers would fit but that for packaging reasons it's better to switch. I may try with the existing lines first and see. Thanks!
