Yea I know, and thanks for that. Im just getting at how everyone says it has an LSD, well no I dont believe there is, jsut like you say, the LSD everyone reffers to is the ATTS. The block may be differant because there is only two treaded holes where the ATTS bolts to but the half shaft support has three and I know for a fact mine doesnt have three. Im jsut getting thrown off by everyone saying it has a LSD. That leads me to think that it has ATTS and a LSD. But I do think your right about the block being differant. I couldnt find the thread about converting it to base. If you would happen to run across it it would be nice if you could point me in the right direction.
