That is what a 2wd transmission looks like without cases.
Here is what a 4wd/ my frankenstein looks like. the only difference is the outputshaft and maybe a few related parts.
I noted that the countershaft bearings were slightly different. i think this is some kind of updateed bearing as the 2wd transmission was about 7 years newer then the r151. r150 2wd on the right.
I also noticed the 1-2 shift fork (common problem on r series transmissions) were different between them. They look noticable different, I really had a hard time picking which one to use. in the end i picked the newer (2wd) one because it was newer and had VERY slightly less wear. hey atleast I have a spare lol.
R151 on left and 2wd r150 on right

I even michmatched the 5th gears.the counter shaft 5th gear is from the 2wd... i think and the output shaft 5th is from the r151f. this was because i was a noob on the press and chipped one of the gears. I ordered a new 1st gear as well for the same reason. i was a little scared about doing this but so far no issues and no weird noises.
One last note. i converted my transfercase to top shift and modified the transmission shifter so that it fits in the w series center console. I had make my own rubber shift boot retainer out of 2 cut and welded to make them longer, and the transmission shifter itself is cut off short and then another piece welded to the side of it so that it clears the little change pocket in front of the shifters on w series trucks... this was on a 2nd gen pickup with no body lift looks very clean with the stock shift "leather" shift boots covering up all the surgery.
