GEC 4" too short

Yes, doing a panel change. The GEC was 4" to short to make it to the neutral bar. For now, we just tapped in a 2 hole lug up high and landed the GEC in it. I was curious if I could do this and run an equivalent sized bonding conductor out of the other hole 4" to the neutral bar ???

I was trying to use this somehow

250.64(C) Continuous.
Except as provided in 250.30(A)(5) and
(A)(6), 250.30(B)(1), and 250.68(C), grounding electrode
conductor(s) shall be installed in one continuous length
without a splice or joint. If necessary, splices or connections shall be made as permitted in (1) through (4):
(1) Splicing of the wire-type grounding electrode conductor shall be permitted only by irreversible compression-type connectors listed as grounding and bonding equip-ment or by the exothermic welding process.
(2) Sections of busbars shall be permitted to be connected
together to form a grounding electrode conductor.
(3) Bolted, riveted, or welded connections of structural
metal frames of buildings or structures.
(4) Threaded, welded, brazed, soldered or bolted-flange
connections of metal water piping.

 
Sounds OK from here, I can't see it. If it was me I would of made a irreversible splice to the GEC outside of the panel then ran the new piece to the neutral/ground bus.

Same here. If, when "stretching" a wire to make that last connection, it's still short, I'll bet that irreversibly splicing in, say, 3 feet cleans up the "stretching."
 
Drive a ground rod into the ground where the GEC will reach.

Connect the GEC to the ground rod, now it is not a GEC it is a bonding jumper.

Now run a new GEC from the panel to the ground rod.

That is exactly how I extended the GEC to the Ufer on the job I am presently working on. Way cheaper and easier than an exothermic weld.

That will mean if OP needed (and had) a 2AWG GEC to an existing elecrode that you would need to run 2AWG to that new rod even though the rod itself only required a 6 AWG conductor.
