So, did you get the FRAM PH6353 or a replacement? When you said the threads were 30mm, I thought that sounded quite large for a 4 cylinder diesel. And you say that you're modifying something to accept a PH8A, but that has 3/4-16 threads. Just about the most common oil filter for many years... If you bought this filter for $28, I guess Spence got royaly screwed...

Glad to hear you got it figured out.
