There is a step by step tech article on how to do this and gives all the measurements etc. I believe it is in "How to Build Tri-Five Chevy Trucks." I have a copy of it somewhere but at this time I have no idea where it might be. Maybe if someone here has a copy they could verify that that is actually where I have seen the article. If it's in there it shouldn't be too hard to get a copy. If I remember correctly it is about the only thing in that book that I found particularly useful.
