by removing the torsion bar, and using a coil over you are putting the load through the shock tower where the car was designed to support the springs through the trans crossmember. the shock tower's aren't up to it. I've heard it bends the car i.e. people have problems closing doors ..panel alignment etc.over time.
good to hear member's experiences with c/o replacements..
Who says the shock towers are not up to it.
My GTX, simply had a piece of 1" tubing welded across the shock tower, inside, on the wheel side. The tabs for the shocks were on this piece of tubing. No snout bars, no other supports or gussets, nothing. The front end alignment NEVER moved, this tells you the shock towers NEVER moved. Performed this conversion on more than one car and the shock tower carries the load just fine.

Monty on a B body the shock tower is beefier than the point the shock attaches to on an A body so I can see it not being an issue .

What holds the back of the lower? where the torsion bar used to go into it? or does it matter?
mine has this simple support. the pin on my K is still used
one thing also done was a bushing was made for the inside lower arm with the bolt hole off center
by rotating the bushing it moves the arm in and out . This helped make the camber setting stay constant thru any travel. Along with the mounting points on my upper arms having been relocated my front alignment is the same on the ground as it is in the air.It thinks it's a strut
Fred, I noticed in the picture that there is no front strut. Was it removed in this picture for some reason or isn't one used? If not what keeps the wheel from folding under?  
If you look at the first picture Fred posted you can see the strut bar , there are 2 tabs welded to the front of the A arm and I'm going to assume his strut is a threaded tube with a hiem joint at the end that connects to the lower control arm .

To properly do this, if you mount a rack, the steering rack should be mounted in line with the pivot point of the lower control arms. If you swap factory ball joints side for side, the steering mount will be too high, to properly line up. This causes serious bump steer issues, so the steering arms need to be bent down, which is how Freds are done.
There are many ways to do this, just have to use some imagination. One way, is to install a different spindle, such as a Mustang II. This allows you to custom build steering arms, but you also need a custom lower control arm. I have also removed the ball joint eye, from the end of factory lower control arms, welded it to the back of a factory spindle, made new lower control arms and built custom steering arms. I did this, because I had disc brakes already for Mopar spindles. I have also cut the spindle itself from a Mopar steering knuckle and grafted that spindle on to another type knuckle...................You can't always buy every piece you need to make something work....you have to build it yourself.....it's called "hotrodding"................lol

When I was thinking about doing the coil over thing I planned on "rounding out" the tbar mount of the lower arms so for example a upper control arm bushing could be fitted snug in the tbar mount. Then install a u-shaped bracket onto the chassis with an extension to the tbar mount with a bolt or something fiting snug into the bushing. This way it would have support in all directions, bushings can be replaced if needed, etc.
Neverd did the conversion though.
Just a thought...

On my early A body I had to get the rack high enough to avoid interference between the front strut rod and the tie rods. Also had to cut, shorten and weld the ends of the ball joints back on to get them roughly where I wanted them and also as short as needed for good turning radius. If you don't shorten them a lot, you will have a very big turning radius. For street duty you will also need disc brakes so you can move the tierod ends out far enough to get proper ackerman angle. Mine aren't out far enough in this photo.

thanks monte  whats your thoughts on welding a plate to the t-bar mount and useing a bolt so it will move with the lca when needed????or is there a better way of doing it...the rack is not a must but would like to do the coil over 
Does not matter how you support the rear of the control arm, some do nothing, just let it hang there. You could cut off a T-bar, drill and tap it, stick it in the control arm, weld a bracket to the frame and bolt it up. Without the T-bar tension bolt, the arm moves freely. Many ways to support the arm in the rear.
