I also share your frustration. I'm installing a cardboard headliner from Carters in my 54. The rear section seems to go in ok. The front section is clearly too big. Not sure whether I should have assemble the whole thing then put it up, or one section at a time like I'm doing. I would be curious to know if all these come from the same manufacturer from the same stamp, or do some fit better. I could easily eat the price of this one if it reduced the frustration I see trying to make it fit.
