dave the pan rails do buldge out about half an inch. Yes there is a circle above the starter. my buddy says on the other side below filter, there are 2 looks like bolt holes but are solid. this makes him think its a 235 full pressure. keep the help coming and i will keep answering. I had 4 friends help me take truck apart and now it is just me putting it back together. I don't really know alot but with u guys help and me being persistent, i will try my best.
