Yes on #10. Its the 5th gear nut on an NV4500 Manual transmission. Most cases it just backs off and the gear slides off too. Some weld it, some pin it, some safety wire it. We've done all three in our shop, experimenting. Its not difficult just time consuming. Our mechanics reverted to "tack" welding the nut on (with a wire welder), on opposing sides so they can grind the weld off later if needed on a rebuild. They tried "tacking" on one side only at first but our delivery drivers managed to break a couple welds so now its both sides. It has worked out well (and quick), no more breaks so far. This is not an actual fix just a temporary stop-gap. Whatever a mechanic can build a delivery driver can figure out how to break!!!!

This is a very good explanation of the problem and its fix for the transmission.
Here is where to look for #9 Fix:

another good idea.
The reason for #3 is braking power. These Napa Cylinders are actually for a GM 1ton. Don't say that though if you buy them. Just ask for the part Number. If you say you want Dodge 1 ton cylinders you'll get the wrong thing.
GM 1ton, NAPA PN# 4637377 are 30mm cylinders
Dodge 2500 pre 1977 are 24mm
Dodge 3500 and post 1977 2500s are 27mm
Thats about a 23% increase in braking power using the GM cylinders and they are a direct replacement. You will immediately notice the difference.
