    The stick out length for a th350 to mate up to a 203/205 is .875" as measured from flange to end of shaft. The 700 that mates to a 208 is right around 3.5". Don't know if they make an output shaft for the 350 to hook up to a 208. Check with Advanced Adaptors, they may have one or know if it is possible.
