I can't seem to find the answer to what i'm looking for. The question is, will a 99si prop valve work with my EG without having to modify the lines?

Also, my friend said he has a 98 DX coupe prop valve, and that it's a 40/40 as well; i'm just wondering if these newer generation civic Prop valves will fit on my EG. I am aware that an integra Non ABS will work, but i can't find one at the moment.

Please let me know, thanx.
