Swapping my 94 extra cab from auto to standard. Need the center driveshaft for an extra cab (longer than in a std cab of course).
Have priced getting one made, found a scrapyard that can order me a used one. But if anybody has a stock oem one let me know.
Will need it shipped to 88007. Don't think i need the support or bearing but if you have one let me know on that also.

 

Is the std cab longbed the same i use to have a two piece shaft but i do have both center and rear with carrier bearing

 

I would think that the extra cab would be longer. I have a 94 extra cab, and a 84 std cab with a longbed. Both have the same length rear shaft.

 

front section drive shaft is 3.5 longer, needed for your swap, just went through the same. 1986 sr5 turbo. had a/t now 5 spd from a 94.
