A lot of years have passed since this was listed. But Jim has a business of selling rear ends and components. I'd encourage you to send him a Private Message asking what he would have available for your car.

Thank you, looks like he does good work. I am new to this site and not overly techy. Is it possible to send message to monzaz only?

 

Yes, hover the mouse pointer over his name and click the left mouse button. There will be a drop down menu open up that will give you options to send him a private message, send him an email, or visit his home page. The home page option will take you to his business home page. You can send a message just to him with any of those three options. Let me know if you have any other questions as you navigate the Classicoldsmobile website. John
