1973 Pickup Radio Stuck Tuner

[fixmeplease]

It ended out I didnt need to remove any clips. I loosened the nut on the outside of the radio (on the shaft) and that must have taken the pressure off of it as it turned then but hard. Then I just kept adding 3 in 1 oil into end of shaft while I turned it back and forth. So its all fixed, the shaft anyway. Thank you again for your help.
