ive had dohc pop front, sohc pop front, s13 sil front and a s15 sil front. and from experience with different fronts only do the pop ups of a s13 sil front everything else is getto and zip tied on with a shade of electrical tape.
trust me just keep what you got after awhile you'll regret it
i got rid of my s15 front end(the dream conversion) for pop ups theyre all getto unless you spend the money and i mean money
