91 Sidekick EGR

Hi all, I am wanting to replace the EGR valve in my 91 Sidekick, but I can't locate it in after-market or dealers. Can someone tell me how and/or where I can get one...... and why is this part so hard to find. Wrecking yards don't even have these cars in my area.... Thank You!

i have a 95 sidekick that still has a good egr valve (wrecked the car so parting out) let me know what else u need and i will be glad to sell it to you.
