I'm not sure about the abs thing, I'll find the part number when I get home from work today. I never had it installed on anything, I believe the guy who I bought it from had it in a TJ.
I'm not sure about the c-clip thing, or if it matters, it's for a '96 & up, you should be able to find the exact application from Tractech, I'll try to give them a call on monday.
Okay, I got a hold of Powertrax and the part number is 2311, it will work on a dana 35, 94 & newer. I believe they're all c-clip, but I don't think it matters. T bent, you have first dibs if you're still interested.
