Re: TH400 Driveshaft Question
You can use a ds like Slug posted but I think it would cost more to make. I could be wrong in my assumption about that.
If I was in your situation. I would get a slip yoke for the th400 then have the ds place make it the correct length with your slip yoke. I don't think there is very much length difference in a slip yoke and a bolt on yoke. I would also have then use non greaseable u-joints. The zerk fitting makes the u-joint weaker and doesn't really affect the life that much. Seeing how everything else is getting built up. Its starting to look like the u-joints are the next weak link.
Mainly need to focus on truck parts, after all you own a truck. So we don't need to get it more complicated with other types of vehicles. I forget the magic number on the one piece driveshaft. But after a certain number it is better to use a two piece. I know that long wheel base trucks are right at the end of that magic number. They also mostly use longer tailshaft version of the transmissions. If not they use the two piece or if its heavier duty than a low gvw 1/2 ton. Short wheel base trucks don't need a two piece driveshaft. Being the length of the driveshaft is okay for a one piece. They mostly use short tail transmissions.
