Need options for front end upgrade for 1966 c20.

[inkfamous13]

Trying to upgrade this 66 c20 i got. Dont really want to 5 lug swap it. Would do disk brake 71-72 crossmember swap. Or 73-86 c10. But options for keeping it 8 lug are what? Any help or info is greatly appreciated. Since you cant swap out lower control arms cuz of the way these mount. Ive been seeing online guys saying theres a spindle swap from 94-99? Idk that uses a 3/4 ton lower ball joint? If this is a option what would i need to do a disk brake 3/4 ton spindle swap and what booster? Also what rear ends work? Theres a guy who has a full floating 98 8 lug with 3.73 gears. This sounds way better than my 4.99 gears now LMAO its bad. How difficult is it to swap in? Or should i just do a 5 lug swap. Im going to do this paint it and resale it. So im looking for what is more liked as far as c20 wise? I allways have bought and keep original. But this front end is wobbly and brakes are sketchy and rear is loose. Other than that its a solid fully optioned 66 c20? Ideas, help,info,direction all appreciated. Thanks.
