4x4 engine crossmember question

[Codyweber]

So a long story short I have a 1965 k10 project (sitting on a square body k10 frame) I need a 4x4 engine crossmember to replace my weird “horse shoe” engine mount I have currently. What I’m wondering is, does anyone make an engine crossmember for these trucks that will work or am I just going to have to pull one from a junkyard? I’ve found a few aftermarket ones but it seems like they are all for LS/LT conversions. Any help would be greatly appreciated.
