Jeep 4.0 in 69 Barracuda

Well, things are paid. Tow truck has been scheduled. Pick up at 10am PST and I should have it by 11am.

I doubt I will get much time on it this weekend. Though I am going to try. I need to get the E-Brake installed and working first. Then I can investigate pulling the oil pan. I doubt I will have time for both items this weekend.
Maybe a bit out of the box, consider a dry sump engine oiling system. You will need a couple of high volume oil evacuation pumps, a remote reservoir, plumbing from the reservoir to the oil pick up. Could simplify your install and resolve any ground clearance issues.
