You talk about us "professionals"?  What we have are the tools and no problem doing is exactly what you ended up doing, grinders, cutoff wheels and welders are your friend.  If you worked on cars professionally like we do, you would get as proficient as we are bumping around sheet metal.  Nice job on that. :drinkingbud:

Thanks! You guys can do this in your sleep, look at a piece and know exactly what to do and where to cut. I have to think about it for 3 days, ask a lot of questions, then get the balls to cut up a new panel. But it's great, I'm learning a lot!

You did really good man, you can't be scared to cut, grind and weld.  I have a 110v & 220v mig welder, tig welder, plasma cutter and torches which covers about everything it takes to knock the ugly out of a body.

Now I TIG welded the cut, I welded it all at once just to see if the distorsion would be bad, wanted to test this before I weld the long one on top of the quarter.

I got mixed suggestions on the quarter butt weld, some say I should jump around to not get it too hot, some say I should just do long welds. Not sure how I will proceed. That why I tested one long weld on the wheelhouse here, with no copper backing or cooling. Not too bad distorsion, after stretching the weld some with a hammer I did a quick run with a flap disc and it show that I got some shrinkage around the weld after the first 2". (maybe I should jump around on the quarter after all...)

Would be nice to get the quarter perfect. I will use a copper backing on that and also cooling paste under the weld. When I do that I can only stretch the weld with a hammer up to a certain point, then I can't get to the back of it.

Heat=warpage  :yes: With a MIG i have spent a hole day welding, another grinding. minimum warp.  :alan2cents:

Quarter goes on and off, many times, it fits fine now, I got the door gap very close now, the door position is fine, rocker to door gap is good and even, it's just the top 4" that is a little bit wider. What is the best way to tighten the gap on top, cut a wedge and weld (I don't even have to fill it, just a slight spread and a weld will probably do it), or try to strech it out with hammer/dolly? First pict.

Second pict, the trunk extension does not fit well, I guess those holes should line up, if I force them to, the top of it bends up so it looks bad from the trunk side, and the top is not flush with the crossmember.
It it possible to fit the extension after the quarter is there or does it has to be done before?
Anyone had to cut and weld an extension to fit?

First one. Cut a wedge and get the gap right then weld it. Hammering it will probably make it less flat and make it spread in more than the desired direction.

Second one. Can you get the extension in there once the quarter is on?

Thanks Tunis! I'll do that.
I can get the extension in there after, the trunk floor and rear panel are not welded yet, I can loosen them up in the corner.
I was just curious how its done when the fit is not great.

Slice that quarter at the top and weld repair it. You must have the rear valance panel fitting the quarter, if that fits then make the drop off fit the quarter.  I see guys modifying the valance afterwards to fit the quarter, that isn't what you want.

Thanks, originally, I was gonna modify my valance, ( a previous owner cut off the flange that attaches to the quarter) but I changed my mind after looking close at it, it seems to be a non original one. The other edges looks funky also, comparing with stock pict. So I ordered a new AMD valance now.

Sheldon is spot on, for every action is a reaction.  :alan2cents:

Done! That was an easy fix, gonna weld it up with the quarter off, then I can use a copper backing.
