need to remove/replace shifter linkage

I just replaced my transmission and the linkage was still attached when I got the tranny in. I ended up keeping their linkage rod attached since I didn’t want to fuss with the pin but now I have to remove the linkage and replace it but I need to do it in the car, is there a trick to removing it while in the car? I know i had to remove the original with a vise while I had it out of the car and that really isn’t an option this time around.

'91 gs-l 5-speed

Thanks for any help

Not really, just gotta get the bitch pin out…Be sure not to slip with the hammer and crack the tranny or anything like that…
