I accidentally bought a GSL-SE oil cooler for my '82 because they look so similar, I'm ordering lines for it now but I dont know which ones to get.. the 79-82 or the GSL-SE ones? Whats the difference? the SE lines look longer, but the FB ones cost more?!

Can anyone clear this up for me?

 

Have your own made, that's even cheaper. My FMOC upgrade in the archives will show you how to. Can't help on any differences between the SE and earlier FB/SAs lines.
