I was checking pricing and availability at AutoZone, Advanced, and Oreilly. I have always used the ms96033 but noticed that Advanced and Oreilly offers a ms96037 which is listed for use with vehicles with aluminum intake. It is also a couple bucks cheaper. Anyone know the difference? Didnt know about this one. I checked it out at Federal Mogul website and yep, they show both valley pan gaskets and designate the 96037 as aluminum for vin 9.
