Well i was "handed" the first part by hand from the ITT representative so technically I didn't order it but their quote stated 9440101, regardless like you said you can do some minor cutting and make to other work. BTW your suggestion for the small terminal 571-2-964286-1 worked great. thanks for all the help.
