    '69t front pull cooler fitting leak

    Oil leak from this fitting. Is this an easy fix? Any leads on where to find this section of line and fitting?

    The tricky part may be getting the lines off, but once that is done those are just factory lines, or look up Brad Davis on this site, send him the lines and he'll make new ones. And do both.

    Stock S hoses won't work. By my observation that's an '84 Euro cooler and later lines on a long hood. (With no visible means of support from an upper bracket for the cooler. At least that I can see.)
    Buy stock 76-89 front hoses from just about anywhere. Super inexpensive.

    Is that oil cooler connected to anything?

    As per Frank's observation. It looks like the top support tab on the cooler is not secured to the back of the headlight bucket as it should be. the resulting movement and vibration might be the source of your fitting failure/leak. Generic lines, but not so cheap any more.

    Any tips (or photos) for fabbing a bracket for that location behind the headlight bucket? Also, do you recommend high temp thread sealant for the fitting connections?

    Those cooler kits had the bracket which mounted to the back of the headlight bucket via a couple of drilled holes. I bought one of the kits from Stoddard back in the day for my then new '78 SC. Elephant still sells a kit, and they might have the bracket...or fabricate. It's two small angle brackets, one to the cooler, one to the bucket, joined by a 6mm bolt to allow pivot adjustment. Never used any kind of sealant.

    Just weld a tab with a hole in it on the back of the headlight bucket to pick up the upper tab on the cooler. I would use a rubber bushing and a shouldered bolt with a nyloc nut so that there is a little movement
