Frame identification help please

[AngeloB]

I've recently gotten a truck and am having a dickens of a time sourcing parts for it. The title and cab states it should be a 69 C10 but... it is a 4x4 with 8 lug axles. it has power front disk brakes and rear drums.

The number I found on the top of frame at steering gearbox is:

70J160536

My main concern for ol rusty at this point is finding brake lines and hoses as it is not drivable now safely. It does have a rough country 4in lift so I know the hoses will need to be longer than factory but I need a starting point.

Any help would be appreciated. thx
