5 Speed options

[llegos]

Hey all, I am interested in swapping some variety of a 5 speed transmission into my 2wd. I am sure this topic has been covered more times than many of you care to deal with but bear with me... I have looked and it appears a NV4500 from a mid 90's 3/4 ton is one of the most common and simple, so i figure that would probably be one of the easiest swaps. What all is involved in the swap? Will I have to modify the cross member? Is there anything needed to get the speedometer to hook up well? How does the drive shaft need to be modified? Would I have to convert to a hydraulic clutch, and if not, what clutch modifications are needed to my current setup?
