What OEM???? Never heard of OEM SS hose clamps. Am I missing something??????
OEM shift bellows will come with a ss crimp on band clamp for the shift cable end, SS hose clamp for transom housing end like shown in this listing. Lots of folks use good quality zip tie for the shift cable end (myself included)

As mentioned take the end off the shift cable in side engine compartment, instead of string I slide a weed wacker wire down the cable outer sleeve, then remove the out sleeve, slide new one over weed wacker wire. Pay attention to how it goes around wye pipe and flywheel cover area.
All this is laid out well in the factory service manual , highly recommend it. As AD mentioned this is a good place for OEM parts, my OEM bellows lasted 18 years without leaking (driveshaft and Shift, exhaust was torn)
