In need of rear jounce bumpers/stops 2017 Taco

Do you happen to have a pair of rear jounce bumpers gathering dust in your garage? I would love to take them over as mine got sliced off during the install of Firestone Air Rite air bags and the air ride is not working out for me due to back trouble. The suspension stiffened up more than my back can handle. I am in BC but have a postal address in Blaine, Wa, which is just across the border from where I live. Just to be clear, there is nothing wrong with Firestone air bags. Looks like very good quality. It's just that my low back is too sensitive and it's not going to get better. So, if you have rear jounce stops you are willing to part with or sell, please let me know. Thanks in advance for any replies.
