Like most old cars, the dash on my '71 Porsche 914 is quite cracked and faded. When I bought it, there was a "dash topper" on the dash, which is basically a synthetic looking cloth material that was velcro-ed on to cover up the cracks and didn't look much better than the old dashboard.
I bought a dash/vinyl repair kit for it and tried to cover up the cracks. They give you a miniature iron and some sort of goop to apply. Maybe this requires a skill that I don't possess, but it ended up looking worse after the "repair."
I thought about buying a new dash, but I don't know if they are even for sale. I looked for old dashboards on ebay and found a few, but they are old and usually have a crack or two of their own and they are bit expensive anyway. Then I found a company that makes dash shells for Porsche 914's (and probably a lot of other cars) and decided to try that.
You need to put something on it to hold the glue in place until it dries. I used some 4 X 4's and duct tape. The instructions recommended bungy cords, but I didn't have any.
Anyway, I think it looks alright. Here is the finished product.
Not quite perfect, but a big improvement, I'd say. The purists might scoff, but I'm turning the car into an electric vehicle, so I'm not a purist.
