No problem,
Glad you liked them. I found them when I was trying to figure what size driveshaft I needed for my truck. Before I found the manuals all I had to go on was other peoples opinions and guesses and mis-information. From what I've seen very few people can correctly answer a driveline setup/design question.. (not that I can either, but now I know where to go look)
Wish more people would read through those manuals, or at least look at the pictures and hopefully read a sentence or two here and there..
