K-Member Removal with Engine in Place?

A spin off from my other thread Odd Suspension Issue "Fixed" Itself

I'm investigating options for repair of the broken LCA pivot sleeve weld in the K-Member on our '73 Dart Custom 225/TF904, and was wondering if it's feasible to pull the K-member while leaving the engine in the car (using appropriate ground support)? Seems like it could work...

The scope of this job has already ballooned dramatically from what I had hoped, and I'd rather not add an engine pull at this time.

I guess another option might be for me to attempt to fix the broken joint in place. I've done a small amount of welding with arc/stick & oxy/acetylene decades ago, and have been considering getting a welder for this and many other projects.

Mopar sure didn't seem to give this LCA mounting point much thought, considering the job it has to do.

Input appreciated, thanks.
