You will need to find an LA 360 oil pan to put it in your truck. Both 5.2 and 5.9 Magnums require 360 oil pans, no matter if it's going in a car or truck. Keep the flex plate off of the Magnum and use it. I don't think the 5.2 has balancing weights on the flex plate like a 5.9, but it won't hurt to use it if your truck is an automatic. You will have to rat one torque converter bolt hole out, because unlike our old flex plates, the converter holes are symmetrical.
