No , the mainshafts for OD are different where 3rd gear rides is smaller than NON OD .

You'll also note that most A body OD's had 904 sized output shafts, I think I still have an OD A body shaft, but the tailhousing for it went out in my last scrap load last fall .



Can I use a OD shaft in the non-OD housing that I have?





No you can't , the shaft I have has a 904 sized output which is smaller in diameter than the non od 833 A body output which is 727 ... unless the first year of the slip yoke A body 833 is 904 sized and you would have to have that trans to begin with.
