Sega CD question - need help finding where a spring goes

[prot0typ3]

I was taking apart my Sega CD last night so I could recap it, and when I took off the CD drive (the Sony version), a short cylindrical spring fell out, and I have no idea where it goes. There are 4 cone-shaped springs with a rubber tube in the middle, and there's a long cylindrical spring where the laser moves back and forth, but the spring that fell out is shorter.
My Sega CD is a model 1. Can anyone help? Thanks

Me too, how can I get another short cylindrical spring instead? wordle
