Hey RDG,
Like suggested, go with a swap from an early 80's 1/2ton. I have an 82 3/4ton that will donate all it's parts to my 66 3/4ton. This way I keep 8 lugs. If you use the whole crossmember, you can use the sway bar from the donor. No offense to ftyler, but you don't need to remove engine or body. Here is what I suggest:
1. Unbolt engine from motor mounts, raise a little, & support. I use a 4x4 with a chain.
2. Jack up truck and put on stands.
3. Unbolt steering draglink and brake lines.
4. Unbolt upper A-arms from frame. Springs-will they need to be compressed?
5. Support crossmember on jack and unbolt.(3 bolts each side)
6. Slide out & reverse process.
Don't forget the booster & master cylinder with brakelines. Check condition of ball joints, tie rods, wheel bearings, and all brake components.
Good luck.
