Technical How do I change from spindle mount wheels to 5 lug wheels?

Someone woke up on the wrong side of the bed.

 

SO CAL polished Buick drum covered disk brake kit would be the best looking disk brakes looks like it includes everything needed except ne hoses yours might work but I wouldn't count on it

 

Nice score on the car its a nice one. if you want to go with drums your going to need it all hubs drums backing plates all hardware and wheel cyl new hoses and check valve Wilson welding has nice stuff and people I know have bought stuff from them and been very happy
