The original post is a picture of the OEM option rack from the factory. Not gonna find one of those though... I do like the one ffrpwner posted, saw that one way back when. I really like the mounting location. But at second glance it very closely resembles one of the universal ones you can get at walmart or an auto store for like $50 or so (i know it's not), but then you'll need to get whatever trays you'd want. That would be one route. Personally I preffer the thule and yakima ones. Don't have a good pic of mine on my car, but here's a few with them:
Keep an eye out on craigslist for one of those used, as they are pretty expensive. But you can come across good deals. I paid $90 for mine with the fairing and 2 bike trays... PS, the fit kit that works is the one meant for the 4dr integra I believe. They don't list one that fits a Z32 because they don't want to be held liable for saying it will work on our cars, then the t tops fly off because of it...
