Can the Heater Core be Bullit Proofed?

I am in the process of replacing for the second time the heater core on my 87 T-Bird. The original OEM one lasted only about 8 years. The replacement I got back then from Trak Auto has now failed after 23 years. I had noticed for awhile the smell of antifreeze so I put some radiator stop leak in hoping that would seal the heater core. That didn't work because the heater core erupted while driving and the inside of my car filled with steam. It looked like the NASCAR winners car after they do their victory burnout or a bad Cheech and Chong movie. Thankfully I wasn't that far from home. What I've found so far is that the inlet pipe came completely unsoldered. It pulled out of the firewall as I was pulling the hoses off. Since I knew the heater core was leaking and I figured I'd have to replace it so I had purchased a Motorcraft HC5 heater core but it has a problem with the inlet pipe not being straight so it will need fixing. I was wondering if there is a way to strengthen the heater core so it won't fail again? Because, I may not be physically able to replace the heater core the next time it fails.

How are the motor mounts? I eat motor mounts, and the cars that are the worst break the heater core hoses as well.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Someone on here made a support bracket and soldered it to strengthen the tubes together.  Someone will chime in when they read this.

I did,, and others have as well but...........
as a great point made by stacks,,, if the motor mounts are bad, the hoses get tugged on and that works the soft brass solder joints bad im guessing.

i have not pulled my core yet that is bad but did order an aluminum one from rock auto.

i will purchase some pieces parts and experiment first though
