Whats a good C4 tranny swap

[NJB71]

what is a good donor truck/van for a c4?? I have 71 w/ a mildly(performer manifold, 600 cfm holley) tweaked 302, currently using a stock 3 speed, w/ hurst floor shifter.

I think any 4x4 truck with a C4 will work. not sure about this because ive never done this swap but make sure the radiator will work with the tranny lines.
