The AC broke in my John Deere. AC is needed a bit more in a tractor

My neighbor is an HVAC tech. We found a hole in the condenser caused
the failure. First braze attempt still had a small leak. The second
attempt, the braze slumped into the line and party blocked it. Now I'm
FUBAR.

Somehow, I need to cut this braze out and weld a patch over it. Or
pull a 180 U off of one end and bypass this run. It is the first top
run on the condenser. Anyone successfully done either operation?

I looked for generic replacements. John Deere isn't listed. No joy
trying to find one based on length and width. For those that don't
know, John Deere selected their tractor color because of the amount of
green you need to buy a part. Anybody know of a place that will supply
a condenser that fits within a certain height and width? I do know a
machinist that can build a bracket.

The easy way is to make a repair sleeve out of the same material and
slide it into place then silver solder it in place by sweating the
joints.Just like doing copper pipe joins.

Since it's the outer tube I would probably do it even easier. Take a
Dremel type tool and cut out one side of the tube where the braze
slumped. Remove ONLY the slumped area and clean the tube up good. Make a
patch that will cover the hole with a slight overlap.
Clamp the patch in place and flow the solder around it.
