APR hat on - We use the PinballInc / Starship Ramps on ANY restoration work. We have had to replace the inferior locally made ramps (as mentioned earlier, not produced using injection molding to original specs). In fact, we just finished an Addams Family and were supplied by one of the poorly made ramps. I think it is best to post pictures in comparison with the PinballInc Ramps as they completely different.

Urgh. that has been another annoying point
most ramps are vacuum formed, that is a sheet of plastic is softened, placed over a mold, and is sucked down to form a shape
injection molded is liquid plastic pumped into a mold
