Well, I wasn't patient enough to wait for a picture.
I went out and decided to just 'figure it out'. Sorry, no pictures, but if it happens to you and you read the below, I think you'll get the idea. First off, a couple of clarifications so the description of the process will make sense. The pedal goes with the LONG end up, using the pivot point as a reference as to long/short end. The spring goes to the left of the shaft with the hooked part going over the top of the shaft and the bottom leg pushing on the short end of the pedal, making the top of the pedal go towards the firewall. The splined pin goes in from the right, through the hole in the shaft and then through the spring coil and finally, exiting out of the pedal mount.
I tried aligning the pedal, shaft, spring and pin with the only two hands I have ... NOT something I was able to do!
Mind you, this whole operation has to be done BLIND unless you pull the assembly or seat out, neither of which appealed to me.
The key to accomplishing this feat of dexterity was to find a small bolt, pin, dowel ... almost anything that could go in the pedal hole from the left, through the spring coil and hold the spring in the approximate position while aligning the pedal, shaft and pin. Whatever you use should only go about 1/4" into the spring (allowing the pin to come in from the other side without interference). I used the plastic sleeve part of a drywall anchor, inserted from the left side of the pedal. The goal is to find something that will hold the spring in place and still be able to be pushed back out by the pin as it is pushed in from the right. It takes a little feeling around with the pin and putting a little pressure on the spring coil, but they all lined up in a few seconds. The pin went right on through pushing the anchor out of the center of the spring coil and then into the exit hole.
Something has to be done to keep the pin from backing out again ... some have used RTV on the end of the pin, some have drilled the pin and used a cotter pin, some have put a cap on it. Me ... I put some Gaffers tape on the head of the pin keeping it from backing out. That should last a good long while.
