Well there is some good news and bad news, with the site being down I did some prodding around on my chassis's. Turns out that the vast majority of them (my recently redone Cohen, Concussion, J&B and PEI) share the same cab height as Fluffy. Comparing them to the CRD there is about a two and a half cylinder gap (I use .03 diameter). So I would be looking at fixing over at minimum, half of the stuff I have made. As of right now I am not sure what I am going to do as free time is hard to come by for me and I am not entirely sure how long it would take me to do it all.
