I swaped out the stock oil pan with a Milodon pan so that it would fit in the RMS suspension
I used the following parts Oil pump pickup
18331
Dipstick
22064
Oil pan
31000
Windage tray
32010
Oil pan gasket (pr)
40750
Oil pan bolts
85025
The first problem was that the flange on the windage tray hit the side of the pan and then the bolt holes would not all line up with the block. I had to bend the flange back to provide some clearance
