Jerry...
I picked up some used bars over a year ago and needed some parts. Paragon told me they could get them, so I sent over what I needed with the exact part numbers...weeks went by without a response, sent a follow-up email, weeks/months went by again with no response. Then, I placed a order for some other parts I needed..Asked Jason to include the sway bar parts....No response.
So...my last order, will be the last order I place with Paragon..After spending thousands of dollars with them over the years...they have lost me as a customer..
You should be able to get the rear bushings from Energy Suspension....
