Front rotor and caliper upgrade options for 4X4

[70']

I have completed the rear disk conversion with a nice 13" Baer kit and I am looking to upgrade my existing disk brakes on the front with a similar kit but have not found anything. This truck is a 4X4 which seems to be complicating the issue. I'm sure someone on here has done it and may recommend a kit.

Is your truck a 1970? If yes, does it have a drum brake front end?

If yes, your best bet is to swap an open knuckle disc brake front end under it. There was a company making kits called Blackbird's Custom Trucks but I think they folded.

If you're the creative sort you can piece together your own kit with OEM parts and a little fabrication.
