Help Shifter Handle Removal 69 Swinger

You only need the feeler gauge installed on the driver side. The shifter handle does not have a detent on the passenger side.
Your feeler gauge must go in at least 5/8" past the top of the sheet metal shim to depress the tab in the shim.
I have been lucky as mine pulls out with no problem using a .010 feeler gauge. It does beat up the feeler gauge some when doing so
