Who should I buy a 727 or 904 from?

I went thru the same issue recently, i had bought the AL pans years ago and they weren't 365, and i went to get one for the dak and jeep and the local guys were either 390 and the other was 575.
I said no not a AL sheetmetal pan, the regular cast al pans with the fins, guy says that is the pan for $575.

I had another issue myself also when it comes to me i'll post it
