Please help!!

[TX '90 ZR1]

Guys & Gals,
It seems I have come down with a disease that requires regular treatment!
The disease seemed to be under control when I was locating items on my car that needed to be put in proper operating order. Now that I have everything working properly, it seems I need treatment by obtaining items that would have been supplied with the car when new.
Thanks to members here I have been able to obtain items (ie: tire tie down strap, wheel locks, bag,etc.) to keep the disease in remission. I have now discovered that I am in need of more!!!
#1- Original valve stem caps for a '90.
#2- Original valve stems, or the chrome sleeves for a '90.
#3- Original tire pressure gauge for '90.
#4- Wheel decals/stickers for a '90.
If you can be of assistance with any of these items please let me know.
