Mustang II upper control arms?

My '37 Ford Street Rod has a Mustang II front suspension (1974-78 Style) It has newer Coilovers with Heidts Tubular lower control arms.
The upper control arms are OEM. Rather than replace the ball joints and bushings I am going to replace the upper control arms with Heidts Tubular ones
which come with new ball joints & bushings.
Here is my question: Can I just put a jack under the lower control arm, jack it up, remove the wheel, unbolt the upper control arm & pop the ball joint shaft loose without anything flying apart? I figure the top of the spindle will maybe tip out until I get the new control arm on..., but is there anything else I need to be aware of..., like how to keep the front end reasonably in alignment while doing the swap so I can safely make the drive to have it realigned??

Thanks in advance!!

You should be fine with a floor jack under the lower arm. Put a jack stand under the chassis somewhere for safety reasons. Take a picture straight down at the upper arm on both sides, or I used to mark the bolt locations using a tire crayon on the chassis so it went back together more or less straight. You will need it aligned after.

Once you have enough weight on it that the coil over springs are loose (not in tension) all is good

Ok..., am I missing something here??
Why do I need the coil over springs loose to do the "Upper" control arms?? Don't I need to have the springs compressed under the load of the car so that things don't go flying apart when I pop the ball joint loose from the spindle! That is why I would be jacking it up from under the lower control arm..., to keep the springs under tension!

True coilovers aren't gonna come flying out at all as they're a single unit. Put stands under the frame, wiggle the coilover while jacking the lower CA until you'll find the spot where it's loose, then remove whichever thru-bolt is convenient. Or in your case, remove the upper CA.

The upper connection of my coilovers connect to the shock tower, not the upper control arm. I do not understand how at any point of jacking up the lower control arm that the coilover would have a spot where it would be loose????

Both of my "coilover converted" cars had standard upper and lower CA's. You "droop" the suspension and plug them in. How else would you think they'd be installed?

I have no idea on your shock tower mounts. With the car jacked up, suspension at full droop, there shouldn't be any (or very little) tension on the unit.

Ok.., I get it. You are talking about the coilover "shock" itself. I thought you were talking about the surrounding coil springs becoming "loose"?

Thanks!
