accelerator linkage

[JtownJoe]

Is it possible to remove accelerator linkage assembly while engine is in the vehicle (30 Tudor). I have the head off & can't seem to find a way to remove assembly, no matter which way I try to take it out it hangs up on the firewall or the block/flywheel housing. Mine has developed slippage in it & I've lost some of the full travel on the carb side as compared to the pedal side.
