I do not, sorry, I spent hours trying to get my door right before I had my body shop do it, might be worthwhile to take it to a bodyshop, and watch the guy do it. Then next time you can, or even just have him do one door.

1) Open the door & remove the old spring remains, if any.
2) Clean & lubricate both door rollers so they turn freely.
3) Clean & lubricate the spring holes & slots(both upper & lower) with silicone grease.
4) Open the door approximately ¾ of full open(this is IMPORTANT) and while working from the bottom of the top door hinge, install the short end of the spring by raising it up on the FRONT side of the upper door hinge and into the top front spring hole. (A pencil type magnet may be useful in this installation
5) While keeping the spring elevated, turn/twist the spring to install the top of the rear spring loop into the slot.
6) Allow the spring to fall/drop down while still engaged in both the top hole and slot, then open the door FULLY and navigate the lower spring front into the lower slot. This may require some GENTLE pulling on the lower spring to the rear of the car, while making certain the upper spring loop is installed with the front part of the loop as LOW as is possible and the back part of the loop is as high as possible, while still keeping the loop fully engaged in both the upper front hole and upper rear slot. At first, you may not think the spring can fit into the bottom slot, but it WILL fit, you just have to be patient and NEVER 'force' the spring, it WILL go into the slot, with 'gentle' persuasion if you have carefully followed these instructions.
7) After the lower part of the spring is installed into the lower slot, insert the special installation tool into the lower spring loop approximately ½" from the bottom of the loop,(some 'sticky' putty on the tool end may help with tool to spring friction) then push the tool toward the interior side of the car. When lined up with the lower rear hole, tap the spring upward into the hole to complete the installation. If difficult to access the lower spring loop with a hammer(due to door wiring, etc), you may use a steel shaft, or you may be successful in tapping the installation tool upward, if friction between tool and lower spring loop is sufficient.
8) Remove the tool, and check for proper door spring operation.

JOe, with your permission I'd like to submit this bit of information to the tips and tricks section. Is that ok with you?

Fine by me. Someone e-mailed it to me last year, so I can't claim ownership. Joe

Joe, I think that was me, and I can't make claim to it either. I got it from http://www.corvettefaq.com
Which by the way is full of great tech/help articles. Check it out

Ok, I've seen these instructions around before... and unfortuately, I have a problem with step 1:
1) Open the door & remove the old spring remains, if any.
What this doesn't tell you is how to get an old spring which is fully in tact out. It assumes the one that was there is gone or mostly gone.
So... how do I get the current one out with that "special tool" that I have?

My first Vette, now owned by JB79:

The instructions assume that the existing spring is broken. Usually when the spring breaks half of it drops off and the other half has to be removed.
I, too, found the instructions that came with the tool somewhat confusing. I used the passenger door spring as a model to see how it is supposed to fit and figured out the installations on my own. It only takes a second – a twist of the wrist so to speak.
After the spring is snapped into place it has to be set with a hammer to lock it in place. Otherwise it will pop out when the door is closed. Joe’s instructions above are good. It actually takes longer to read the post than it does to replace the spring.
Just keep playing with it. You’ll find it’s like riding a bike. Once you get it you’ll never have trouble again.

I think the instructions for removing the old hinge spring are in the tips and tricks section!
