hey there, i have a 1980 fj40, I recently converted it from vacuum operated 4wd to manual 4wd engaging.... worked a treat but just when I was fiting the lever to the wee shaft out the top of the transfer case or high low the wee shaft sliped into the box

I have tried magnet, tried everything I could think of bar pulling the box apart!
I have had no luck.... so I need to open up the transfer case...

If I unbolt the rear of the transfer case, will I have a pile of parts fall out? Or will i b able to unbolt the rear of the case pull it off, poke the wee shaft back up an put it all back together and fit the high low lever back ont and go play!
Thanks!!!
Chris
