Looking for some help please - 5 Lug Convert

I am in the process of converting my 1987 Mustang convertible from 4 lug to 5.
So far so good except that I made the mistake of having the car in gear when I rotated the axle to reinsert the c clips. Unfortunately the spider gears slipped out of place and fell out of the differential.
I read on this forum how to put them back in but I am a little confused.
Any assistance is much appreciated.
Thank you,
Jack

First and foremost, I am very happy I found this forum and any help I can get.
I bought this car from my dad about 15 years ago. I went through a divorce and was unable to maintain and or drive it for many years. She has been in the garage under a car cover all this time, only starting her occasionally. She has never seen any bad weather and always kept inside.
I recently refinanced my house and pulled some money out to get this car in shape. Mechanically its a sound car, having only 75,000 original miles, 12 of which I put on her. But she definitely needs some tlc, no interior, new roof (convertible) and I decided to convert her from a 4 lug to a 5.
I hope I don't regret it!
Although this video is helpful, my differential differs in that there are 2 S shaped springs in the middle of the 2 side side gears that prevent me from placing the spider gears in as shown.
Any other suggestions?
Thanks,
Jack

oops, needs a new interior and rag top
