np203 or 205??????
 

I have a 1970 chevy 4x4 k-10, and i wanted to find out what transfercase i have? Also when i move the rear yoke side to side there is some slop. So i want to know if there is suposed to be some slop or no slop at all?

Thanks for all the help James

you should have a 205 but just in case go here. they have pics of each that will help you out http://www.advanceadapters.com/catalog/040.html

Thanks that helps me out alot. So from what i can see, i have a np205 because i have the plate with the three holes in it. But the only other question i have is if my transfercase hase to much slop? Is there anyway of checking the slop in the transfercase? Thanks again James

The yoke is supposed to be tight. Be sure the big nut that holds yoke to the shaft is tight. You will need to unhook the driveshaft to get to the nut.
