I'm trying to fit one in for a customer and it doesn't fit. The rear sealing area is too small and contacts the cover before it can be fully installed on the unit. This week I will contact Moroso about this. In my experience most boxed oil pans are terrible at how they fit initially. engine and/or chassis. The problems aren't usually with the really expensive stuff (custom builds like Steph's) that most people don't want to buy, but when you factor in the time you spend assembling a cheaper pan, then $600 a pan is no more bad deals. Think before you buy. Update 4-2-08 Spoke to Moroso and they said that sometimes they twist and suck when welding. I was told to send it back and I wanted to, but figured to get this customer done I asked my supplier to ship another one the next day. It has also been changed. Although not that bad. Maybe we can get it working. I'll update again as soon as I know something. Update 4-8-08 Went through 3 pots with the same part number from Moroso and each had the same issue. I ordered Milodon #31125 and it is perfect for the standard installation procedure. The Milodon Pan doesn't have the "bells and whistles" that Moroso had, but the fact that it can be used makes a big difference.
