Hemmings and the archives on the Imperial site can help with most of the questions you have. 1.Radio-many vendors are listed in Hemmings for this sort of repair. I would stick with repairing and add a modern one. You can't beat the appeal of the old scanner these radios have which I am assumming yours has with the floor button control. 2. Window motor. Those are avail through various sources but I have used Hyro-E-Lectric which is listed in Hemmings. Have you checked to make sure the assembly is not gummed up and the motor just can't move it? Could it be a switch? 3&4. Hemmings has sources for these as well. 5. Hemmings has vedors listed 6.Hemmings vedors and this fine Imperial mailing list will hopefully give you the answer.

(orig. cream white with a tan interior), 440 CID V-8 Self-Introduction: I purchased this car in 95 and did a body restoration, new top, tires, brakes incl. master & wheel cyl.& hydraulic lines, dual exhaust incl. exh. manifold gaskets & new carb. This is a really nice driving car and I intend to keep it as long as I can keep up with the difficult parts aquisition. She's been the star of many 4th of July Parades on Martha's Vineyard often carrying war veterans and other dignitaries. Currently, none of the vacuum actuated controls work. No dispursl of heat to the dash, vents or the floor, no ac working. 6-way power seat works well and the interior in generally in good cond. Let me know if you would like to have a photo or this car e-mailed. 1. Looking for a good replacement radio (or a source to repair the existing one). Would prefer a more modern replacement to the radio that would not require retrofitting or cutting the faceplate on the dash. Do you have a source that would fit a modern stereo into the existing old radio case? 2. Also looking for a replacement window motor driver's side rear or a source to rebuild the existing motor. 3. Would like to get a new "rear deck cover." For a lack of a better name, this black vinyl sheet is stretched across from the top of the rear seat to the rear body cowl and serves as a dust protection for the inside of the conv. top while it is down and while the top is up, serves as a rear deck. 4. Also could use a new parade boot for the top. 5. I had a difficult time securing a pair of rear brake drums for this car and would like to replace the marginal used ones I obtained with new ones if available. 6. Desperatly need new rear traction bar bushings and can't find a listing. Any suggestions from club members would be appreciated. As this is the only Chrysler I own, I have no spare parts to offer. Thank you for anything you can offer for support.
