My bad, I though I did.
Its a second gen dodge ram master. From what I've read, the 1500/2500/3500 used the same one, regardless or gas or diesel. Its a 1.25 bore, m10x1 and m12x1 fittings. The 3.5 used a different master than the 3.3, but with carefully manipulating of the hard lines, i've gotten a 3.5 master to fit a 3.3. So I'd imagine you can make the 3.5 lines fit the dodge master also. The Nissan is a 1" bore, and both ports are m10x1. So the front port on the dodge will need an adapter. Hood doesn't close all the way unless you remove some of the lining on inside; the dodge master sits higher up. Could put washers between the hood and the hood brackets also.
Here is the master: https://www.partsgeek.com/gbproducts/HC/1968-09047407.html?utm_content=HC&utm_term=1998-2001+Dodge+Ram+1500+Brake+Master+Cylinder+Dorman+M390426+98-01+Dodge+Brake+Master+Cylinder+1999&fp=pp&gbm=a&utm_source=google&utm_medium=ff&utm_campaign=PartsGeek+Google+Base&gclid=Cj0KEQiAlsrFBRCAxcCB54XElLEBEiQA_ei0DEz_UIhNV5Me8XA2-z1XdRI_F6LXFLpE-vEqNb3iTG4aAoZ18P8HAQ&ad=47433965532
