The KE70 is just like a AE86
Its rear axel points ae the same and its 5 linked so all the ae86 rear links will bolt on along with the rear suspension and the front (although, I think the front suspension need the ae86 TCA not sure ask Simon 86 here).
As for the engine, if you get a ae86 x member you can drop a 4age straight in, no messing, and also the std T50 Gearbox slots in to from the ae86, just make sure you get the gbox support that bolts underneath the car. The only hard part is the wiring as the ke70 uses a carb set up, and you need to modifiy the fuel tank or just run a 4age on carbs.
also, the engine in the KE70 uses a cable clutch but the ae86 uses a hydrolic clutch so that needs sorting to.
after that, wheels, and front seats from an ae86 all fit in including rollcages.
boom, cheap ae86 hence why I want to do it!!
