hello, i have 2 89 hatchbacks 1 is a DX dont know what other is. One of them has a d16a6 in it and im wondering what i have to take out to swap it to the DX, and what i would need to do to get it to work, the d16 came from a 91 crx si and the reason im doing this is the car with the d16 has alot of bodydamage. Thanks
