Are all 1st Gen CRX parts interchangeable?
The 1st Gen was first sold as 1984 model in 1983. For the 1986 model year, the CRX got a slightly different interior. Honda also changed the electrical connectors in the 1986 model, so some electrical parts from the 84-85 car will need modification to fit on the 86-87 cars. There are some subtle differences in the front fenders, front and rear bumper covers, body cladding, and header panel between years and models.
