does any of the coilover kits available for C10 fit K5's?
or are they completely different (i don't know how much parts sharing GM did between models in that era).

I saw someone who makes a whole frame with coilover suspension (switch suspension), kind of pricey but in the end with the coilovers and an integrated fuel tank for EfI maybe that actually is a money saver?

I know i'm daydreaming a bit but that to me is part of the research helping me decide if i want to committ.
The alternative, to be honest is to buy a 3-5 year old jeep wrangler and bolt on ready made after market parts. Easy and relatively cheap and you get to do something that is functional and a bit personalized. Easy to get parts if something breaks.
