Viper book is still available, but with a price drop!! $20 shipped
Springs are still available at $75 plus shipping
Radio is still available at $65 shipped.
I recently installed the radio to confirm the cd changer works on all 6 slots, the volume button is finicky and does require moving the knob slowly to ensure the volume moves the direction you want it to go. I have a video of the radio operation on my phone that I can text to any interested parties.
