Re: t-19 clutch questions
I hope that Its just a typo that you are ordering a ford t-18 input shaft, the t-18 input will not fit a t-19. you need to order a ford t-19 input shaft, there are at least several variations available depending upon what front bearing is used and spline count etc. these include: t19-16a, and 1309-085-xxx. I would take the t19 input shaft and bearing, and the jeeps input shaft to your supplier so that they can get all the measurements required.
good luck, jjc
