I just put a 20-500 on my 18 Rebel 5.7, and it does NOT actually fit right. Because of where Dodge put the 4x4 front transmission (So a 4x2 should be 100% fine.). There is actually not enough room to really move the filter into/out of the filter spot. It is the correct contact/thread, but too tall to actually fit the gap. I had to finagle the filter into place, and basically take advantage of the threads fitting into the hole for the threads to get the filter to even line up, and still had to force the first turn or 2, as it was pinned between the threads, and the transmission.
