I don't think I've ever seen a shortshaft 70. That's a triple? I think they only offered longshaft versions.

99% chance it's a 20" shaft, known as 'long shaft'. 'Standard' shaft is 15" (also known as 'short shaft), and 25" is called 'extra-long'.<br /><br />Hope this helps......<br /><br />Chris................
