No, they are not interchangable.
no
Yes
No, not all parts will fit.
yes
No, the fenders and bumpers from a 92-95 Honda Civic 4-door will not fit a 92-95 Honda Civic 2-door. The body styles have different dimensions and mounting points, making them incompatible with each other. If you need to replace parts, it's best to use components specifically designed for the same body style.
no your sedan lights will not fit coupes
if the Honda civic dx is a 92-95 then yes.
NO. It will not.
yes
No, none will fit.
Yes front end on a coupe and hatchback are the same
yes it does fit...94-97 have the same bumpers. Someone else answered the above statement. I answered below, and have actually done this. 94-95 have the same bumper, pretty much exactly. 96-97 has a different bumper, but it can fit on the 94-95. A 96-97 bumper can also fit a 94-95 bumper. The bumper brackets are different though between the two models. Whatever year the bumper is for, get that same year bracket.
