I am restoring the front suspension on my 70 Roadrunner 440 six pack car, I removed the lower control arm bushings last night and glass beaded the control arms. I would like to hear from users that have already done this.

Where is the best places to order the new bushings? I was looking at Hotchkis suspension and the picture they show for lower control arm bushings does not look like a direct replacement like they advertise? There are a lot of companies selling suspension kits, which is the best fit?

Opinions on polyurethane versus rubber bushings? What are the down sides of polyurethane?

I know there are a lot of questions in this post but I only want to rebuild this once, so any help is appreciated.

Thanks
