Quarter Panel

Need to replace the back 3' of pass. quarter on 63 Impala 2 door ,I got a panel off a 63 4door. Now I'm trying to go at the best way to do this ,I pulled donor panel from the bottom seam up to the trunk lip (spot welds).I was thinking of the vertical seam just right behind rear tire but my buddy was saying to use as much of panel as I could which would put seam at the front of wheel opening any advice here would help me tons

I'm not a body-man, and I'm not a welder, but I don't think I see any value in doing what your buddy says.
Looking at the 2 options you mentioned, both leave you with sort of a 70/30 or 30/70 scenario of replacement metal vs original metal. Know what I mean? In that regard, I don't see how one is definitively better than theh other. More pictures might help.
You aren't doing a butt-weld are you? I was assuming a little overlap with one side crimped.

If your other metal is fine, and you're not replacing the whole quarter-panel, I'd opt for the cut behind the wheel-well as you mentioned.

I would save as much of the original metal as possable and just replace whats bad.

Exclamation

I THINK the only way to do the vertical is butt weld ,would a flange tool work on the radius of the panel ??OK kid showed me how to do the pics. I was going to go kind of like the green tape is.Would it be a pain to try and finish the top line in that con-cave area.All advice is OK by me

Flanging the whole vertical line is without a doubt more work, but I think if you first make short, horizontal cuts (length of the flange) on the old panel it will work nicely. I'd think you'd do that at each contour/angle change of the panel. (like, the top and body lines)

Also, I think flanging would really really give you a greater margin for error, allowing you to focus on all the other mating-points more.

I won't mind if anyone else chimes in and contradicts me here. Feel free! I've done similar welding on my Impala but I am NOT a trained welder!

Can't decide which way is better or scrap the idea and save for a new whole quarter .Seen on u-tube a guy replaced them and had bad alighnment in the treunk and door area (bad gaps).This was another way I was thinking donor panel is just sitting on the bad

have you thoroughly checked the original wheel lip area for any rust? For me, if you had some rust there it would affect the decision.

I guess after seeing that video you now know that if your quarter-panel replacement includes that area next to the trunk lid that you'll want the trunk lid installed when you line up your replacement quarter-panel section.

Since you brought up the whole quarter panel option, I will say I do think it's worth saving for.
Another bad thing about doing a section is you need to be more careful about creating a heat-warp from the welding right in the middle of the panel.
