That seems to be the issue. From a step by step process it seems simple enough, just requires that ugly "P" word.
I've always heard start from the top and work down. Headliner, aile panels, pillar post moldings, dash pad, door panels, rear interior panels, carpet. That is the plan I intend to take, but I am looking at $300 to $500 for installation of the Headliner and the new Vinyl top. Just thinking I can do it and use that money elsewhere.
