Devlin....The agony office is open, but needs to know a bit more about the bike. If you can give a little more information, then a few more folks with wide experience of these machines will be able to assist. If it is a standard bike rather than home built special, then when you say "hybrid", do you mean a separate engine and gearbox, but the gearbox bolted to the back of the engine? If so, you have what is known as a plunger, or semi-unit bike.
The gearbox can be dismantled almost entirely while still in the frame, so sorting the kickstart will be easy, plenty of information on this Forum, BSA Service Sheets, YouTube, Haynes.

Additional..Reading through your earlier posts, looks like the engine is an A7 Longstroke in a plunger Frame. This engine has two rocker boxes and a pair of cylinder head studs at the back of the barrel, above the magneto. The entire primary drive, with the exception of the crankshaft drive sleeve, is common to all plunger motors until the end of production, so later model A7/A10 Plunger will fit. The drive sleeve varies depending on the year an oilseal was introduced, earlier have a scroll, no seal. With the later oilseal they are smooth, but no seal and smooth sleeve have been reported, so at a pinch any later more common parts should fit. Triumph bits only fit the later S/A models with a single row primary chain.
