Not on a Mopar product, but I bought one for an AMC 304...worked fine in the end, but the flanges weren't flat when I received it...it was tweaked a little on the long axis. I ran a large punch around the perimeter to flatten them out and walked it down on the bare block before I did the final install...hasn't leaked yet. But, Bob is correct...you get what you pay for.
I also used one for my 5.2 swap (360LA pan) from Jeg's...I think I paid $54 for it and it fit perfectly.
