well, just a FYI, I have almost everything, still waiting on a few more parts...like my diff cup, that didn't come with the hyper diff, and a few small items.....I believe I have the rear part of the diff figured out ( the cup part) and presently the ring gear is getting drilled & tapped by a friend at work in the machine shop, and the only other thing I think that will needed to be modded is, cutting the stock outputshaft & drilling a hole to accept the pin that indexes the internal output gear, so so far it looks like it may be easy to do.....hopefully I can get pics this weekend...if everything comes.....I'll keep you all updated, as well. Pics to come.......
