perhaps you've seen my other post to suggest the speedway kit which i now know does not exist. i too have to make a drive shaft. i bought a 10 spline coupler on line for half what the vendors want, then went to shop for tubing. the local farm place that makes pto shafts could not come up with the right size, so i went to another place that only builds drive shafts only to find they dont have it either. its been a few months back so the sizes dont come to mind, but ford used a heavier wall for that size tube that is available. this all the DOM- drawn over mandrel tube that is claimed to be the only thing acceptable. to get the same wall thickness you need to go bigger, so the coupler is too small, or go thinner wall and cut the coupler to fit and keep the burn outs to a minimum. my friend who is a airplane guy says 4130 tubing is just as good, much more options in that market for sizes. the other problem with making my own is i'm not sure i've ever seen a good front shaft to cut off and weld into a bushing , then on the shaft. every one i have is bad on the front bearing race. i even ran an add on the model A adds for a front 18" or so, beca.use the A's have a weak design on the back, four million were made, but no response. i had finally thought to just buy the speedway kit and be done.... but i guess not. there was a thread on the hamb with the original 32-3-4 wall thickness
