I wouldn't use stainless in that application.   The factory parts book shows 
them as being 7/16 x 20 x 1 1/4, but it's not quite that simple.   Our 
driveshaft bolts have an unusually long grip-length to thread ratio.   Normally, a 
bolt of a given length has only a certain percentage threaded, i.e. 80%, and the 
last 20% is an unthreaded shoulder.   Our driveshaft bolts have something 
more like 50% thread, 50% shoulder, and it is very important that the bolt is 
shouldered where it touches both the driveshaft, and the mounting flange on the 
hub or gearbox.

Fortunately, Aircraft Spruce sells The Good Stuff--cad-plated AN 
(aircraft-spec) bolts of the appropriate length and with the appropriate grip 
length--stronger and better than the best you can get at a hardware store.

What you need exactly is AN7-11A, which is a cad-plated bolt, 1 7/32 inches 
long, with a 9/16 inch grip length, and an undrilled shank.

Cost is a very reasonable $1.19 each, and here's a direct link to their 
website:

Your matching cad-plated nylon stop nut is the AN365-720A, which costs 78 
cents each.   Direct link to the ordering page here:

There you go!
