My 235 came with this engine mount and this alt fit perfect. I used a spacer at the water pump and cut the end off this bracket arm (Spectre Performance 42263 Alternator Bracket Kit) and drilled a new hole. Belt...Gates TruFlex V-Belt 3/8 Inch x 41 Inch - 1410 Alt...ACDelco Silver 334-2110 Alternator. As a gauge the center hole in the ALT is lined with the motor mount bolt.
It looks like your belt Is off alignment a little. You could shim the pulley out somewhat to get it lined up.
