I purchased a DOHC JDM cable LSD ZC and willl be doing the ole' ZC 3, 4, 5 (possibly cx/vx 1.066 4th, and I may try and use ZC 2nd if Bense is successful) in an Si z6 tranny, however, I want to use that LSD diff as well. I don't want to mess with a haflshaft, I find it unnecessary if the car will have LSD anyway. I figure all I need to do is find inner cups (end pieces that slide into the diff) that are the same length as my civic ones, but have the larger spline section, slap em on my civic axles, and call it a day. The math makes sense, the question is as follows:

Which axles do i need to pull those inner cup peices off of to work in my application?

I have heard 90-93 DA is what I need. I also hear first gen integra is what I need. Anybody happen to have some solid insight?

Anybody interested in trading a DOHC ZC LSD for an obx or quaife or oem meant for an s20 case to save me the hassle?
