K frame removal on 73 Dart 318. How hard is It?

Don't try and support the engine underneath. I believe it's pictured in the service manuals. There is a tool you install that supports engine weight that rests on the frame rails. I "made" one so to speak. used lots of rags on the fender aprons, and cut a 4x4 (you could use a pair of 2x4's) across the flat area of the fenders. Then cut some 2x4 braces right length to sit on the frame rails and bolster the 4x4. Jack up the engine with jacks under or picker above, and rig a chain on the water pump/ intake bolts, etc and "rig" that chain tight over the 4x4 then let the jack down. Worked pretty good.

If you don't want to undu the brakes, separate the lower ball joints, leaving the brakes and spindles hanging from the upper arms. Tie them up with wire, etc. Pull the column / steering coupler and of course the engine mounts.

T bar removal. There's a tool for that or you can make one, but I find it easier to release the lower arm pivots, then get a 2x4 and crowbar and pry the arm to the rear which forces the T bar to the rear. YOU MUST remove the retainer clips at the rear of the bars

IF YOU DO NOT have one you need to go to MyMopar and download a free service manual

This is WAY easier with a hoist!!!
