NV3500 swap, which flywheel and clutch with original 69 350 block

[MYOUNG]

I have a 69 GMC 2500 camper special with the original 350 motor that has been rebuilt.

I just picked up a NV3500 out of a 1994 chevy 1500 out of my local junkyard for 400$ and its in really good condition. I have been looking around for a consensus on exactly which flywheel, clutch, and starter to use but I have got a lot of conflicting info on various sites so if anybody had done this swap and knows exactly what works with the older block/crank that would be really helpful.

153 or 168 tooth flywheel needed ? I read somewhere that I needed a flywheel out of a 79-88 truck.

Can I use my original flywheel with a new clutch for a 94 V8 truck ?

Do I need to change the starter motor?

I have already figured out how I am going to set up my hydraulic clutch.

Thanks
