[SEL] FM Z 3hp trouble

[Tom Smith]

Well, I got a Maytag 72, so I suppose I have two examples of the 
bottom of the barrel.

It looks like whomever cast the repro bracket would have gone to the 
trouble to do it right. My Z was also missing the gov parts so I was 
missing more than just the bracket.

I've got a milling machine and could have made the cast iron assembly 
work by milling space under the bracket to clear mounting nuts but 
wanted to keep it "original". Course, the cast iron assembly with the 
Bosch mag isn't original to my later issue engine anyway.

Have a nice weekend and thanks again for your help,

Tom
