The dealers contracted out local custom 4x4 places to perform these conversions back in the day for the 620. I had a 74 620 4x4 truck.
They did use jeep suspensions under them. The front and rear axles usually are 5 lug and the front has manual locking hubs. Mine was converted to a twin stick transfer case, but it had 2wH, N, 4wH, and 4wL not in that order.
The engine and tranny are stock Datsun. Front steering arm has a welded in extension, and the leafs have shackles on theme to raise it.
They did a good job back then for the 4x4 part of it. Some even kept the front disc brakes on the 77 620. It is pretty rare so keep it looking good.
