A/C line melted on MAC Headers

I had that same problem on my '89 GT. I have never heard of it happening with our bodystyles though. I guess it could be something else to consider before buying LT's in the future.

If you cannot reroute the stock hose away from the headers, reuse the aluminum connectors to reassemble a new hose (maybe longer) routed well away from the headers... replacing stock pieces in the A/C system will change the refrigerant requirement (weight)... but if you don't get A LOT away from the original hose routing you will be OK... you can put some insulation as well to do a neater job...

I rerouted all the hoses on my Hardtop 1968 when I installed a sanden conversion from Classic Air... I installed a sight glass in the liquid line to get a proper charge of refrigerant...

All I did to fix this was pull it up (carefully) so it didn't sit on the headers. I used a zip tie to hold it up and off the header. As long as it's not touching you are fine. No reason to length it, reroute it. I suppose if you were really worried you could wrap it with header wrap so it had a little more insulation but the key here is to make sure it doesn't lay on it.
