It will work with minor modifications. Use the frame's year body mounts. Font bumper mounts need to be reworked. Front brake line locations might be different, Transmission crossmember might need to be drilled.
If you can tackle a frame swap then any issues you come across will be nothing to you.
My 86 K10 has a 79 C10 frame under it and before that one I put a 78 K10 frame under it.
