I failed to install my wheel spacers this weekend because of these lines. I'm stuck on one part and looking for some guidance. I am using stock wheels + 255/75 MT/R's and 1.5" Spidertrax spacers

I have my grinder for the pinch welds and I have the ac lines for XK's w/o rear climate control so I'm good on that front. Where I am stuck right now is what to do with the heater lines.

Did you guys snake them back up into the engine bay and just connect them together? If you did, what size are the lines, 3/8" or 1/2"? If I can just connect them I was just going to buy a brass barbed fitting like the one linked below, will that work?

Obviously wont need a five pack but you get the idea. Thanks!
