Ok The headliner in my burb is falling down and is not the best of condition. What or where can I find a replacment? Or what have you all used?

Have any of your put in a rear A/C unit out of a later model for more efficent cooling? I would be interesten in seeing some pic's and hearing some details. I'm not convinced that a dash unit will effectivly cool the big passenger compartment.

Thanks in advance...
