Improvement 1979 C10

[nacho_73]

Hi

I'm working in my 1979 C10 Custom Deluxe. I'm installing a 350 engine, 700-r4 transmission, wilwood brakes in front and 5/7 lowering kit.
I'm thinking to improve the differential installing a Differential Locker and disc brake.
Could you recomend me the best way to do that? with several kits like Yukon gear or Wilwood convertion kit .... or change al rear axle whit locker, disc brake, line and all from a newer silverado.

Thanks a lot
