Honestly, we had the same complaints when we added Pre-92 Civic to the CRX forum. The explanation was the same then as it is now. The CRX is the same chassis as the Civic from those years, and the folks with older Civics would have been better served by the CRX forum than the Civic forum so we made the Civic forum '92-up Civic.

Adding the EL to the forum is obvious, and the del Sol is just the CRX everywhere else in the world. Everything mechanically is the same as the EG Civic and the B16 is also in the '99-'00 Si so really the only thing exclusive to the del Sol is the top.
