I'm wanting to install a headliner and have several questions. First, where can I get some detailed instructions? Second, can you tell me how difficult it is to put one in -- I've never seen this done and have heard that it's difficult. I have done a lot of work on this car, such a replacing the hydraulic system and overhauling carburator, fuel pump and distributor but the headliner has me concerned about whether I can do a good job.?? Thanks for any information. Bernie
