I have a couple older model Integras, and aside from the SB Integra where the bridge is recessed into the body a bit, the other ones were all pretty standard bridges, so pretty much any bridge would work as a replacement. You may need to drill new holes on the bass, though. I have had a Schaller "Roller" style bridge and Gotoh bridges installed on my Integras and they worked out great - but I did have to new holes drilled. I just had them professionally installed since I didn't want to screw things up!
