I've looked and I know there's a weight difference in the HF and the others but I'm wondering if a 90 Si rear bumper support will fit my 89 DX? I searched, but in the mass of random threads I couldn't find anything. I've read that theyre all the same, but I'm unsure of what to believe. Closure please?

 

Nothing from the Honda gurus? Here's another one for you. I got a new left fender in the mail and noticed that the DOT labels read 88-91 Honda Civic Coupe CRX. I matched it up and its exactly the same as my old beat up fender even the molding space. So i came to the realization that if the sticker is true and all the fenders are the same, then they 90-91 fender moldings, though different, should fit my 89 fenders correct?
