completely rebuild front suspension?

I'd pull that K for three reasons:
#1 you can't truly inspect it easily if it's in place, and given the tendency of these cars to crack lower control arm mounts and such, you'll end up welding washers on there and all that good crap if you know what's good for you. Gusseting the K and fully welding it does add a measure of stiffness that will be readily apparent when driving.

#2. You can completely and easily build the front suspension out of the car, which is far more comfortable with the K on work table or even a shop floor compared to laying under the car with crap falling in your eyes. A couple pieces of grit in your eye or a trip to the hospital (with requisite bill) will make you regret doing anything under car you don't have to, once you've done the job without it.

#3. It's easier to clean everything.

Unless you're the type to insist on rebuilding an axle under the car, pull the upper control pivots, pop the steering coupler and motor mounts (I lay a 2x10 across the fenders and hang the motor with ratchet straps), back off the adjusters and drive out the torsion bars, and pull the four K bolts. Easy as pie.

Pro tip: drill a 1/8" hole over each K bolt and douse with penetrating oil before you start. reapply hourly. Plug hole with silicone when you're done.

And you don't need to worry about the marking the rear of the torsion bars. They're handed and won't fit if swapped side to side, and the twist directional force applies the same way same regardless of which end faces front.
