Since you have a 1987, finding the coach number may be a bit of a challenge. The coach number is frequently on the inside of the engine bay doors during the 1983-1989 model years, on the design floorplan from Newell, and typically on the inside of some of the interior trim pieces. The coach number would be a 3 digit number between about 120 and about 159. The VIN for 1987 coaches would start with 1N9912X8, then a check digit, then H10110, followed by a two digit sequence number which indicates the order in which it was built during the 1987 model year. There were at least 37 Newells built during 1987.

I am still attempting to correlate VIN numbers to coach numbers for the 1983-1989 era. I have some data but I also have some conflicting information.
