I an trying to fab up supports for the bottom of the door jams (blue in the attached sketch.)

The old ones were rusty—shocking I know.

I will be installing a Brad Mayeur stiffening kit (red in the attached sketch) and so I am thinking that because of the strength of this reinforcement I can probably make the door jam support a little shorter (not go to the bottom of the long). This will leave clearance for the lines if I decide to run a front oil cooler later. At this point I am thinking rear passenger fender for a cooler, but I want to get feedback on how they work from Perry Kiehl first

Alternatively, I can make it go to the bottom of the long and later maybe drill holes in the side of the support if I decide on a front oil cooler.

See the sketch below to visualize what I am talking about.

I will build the support out of 16 ga to make it pretty hefty.

My question is what is the outer diameter of the biggest oil line I could possibly need for a non-track 3.2?

Thanks,

I did all mine with AN 12 which most people feel is fine for a 3.2 street car. I'm pretty sure I just used a 1" bit to make all the holes along the door sill supports and the front trunk.

This pic shows Brad's reinforcement kit and oil lines - Chris Foley thought that with Brad's kit the lower support was not necessary. Nor were the triangle supports, but there were some extra weld rosettes on the long reinforcement.Click to view attachment

You guys rock, thank you!
