I have the updated intermediate steering shaft (part #19153614) and the green bushing (part #88963617) which were both updated versions GM put out to correct the steering clunk and slop. I bought these for my 2006 ss clone I was building, but no longer need them. Both parts are brand new uninstalled in factory packaging. Only taken out for the photos. The cheapest I can find them online with free shipping is $69 for the iss, and $32 for the bushing. These are OEM parts from GM.
I am asking $75 shipped and insured to your door. Paypal accepted as gift or add fees.
