While at the machine shop today I spoke with Doc about oil pans and I think we agreed that the Kevko M302 will be the best bet for what I am trying to do. I will get it and the pickup ordered when I get paid again at the end of the month.
I run the Kevko pan. Its six quarts plus the oil filter capacity. Great ground clearance too, does not hang below k-frame. You don't have to run a windage tray either.
