    Crossover Tube Replacement Options?

    I damaged my COT trying to remove a stuck burp plug (still stuck). The bung the plug screws into is now separating from the COT and leaks. What are the alternatives for replacing the COT? Can we use one from another 4.6l powered car? Which one, which year? Also, I need to clear a centri supercharger. Surely someone else has figured this out already. Thanks.

    I bet you could take it to a welding shop and have it repaired for short money if it's only leaking at the bung.

    Depends on condition, but I've seen average $150-$250.. I sold a rusty, but not leaking one and I sandblasted it and it was still strong and not thin and for like $75 last summer to help someone who needed one.

    I would get an ON3 Xover delete kit , eventually the Marauder specific tubes will be long gone , and people will be wishing they had got a Xover delete kit when they were available.

    Do you know off hand if these kits work with a procharger type setup? I'd like to clean it up under the hood, hate the look of that cross over tube.

    I'm pretty sure they do, from the research I did. I'd like to install one in my car as well. Hopefully someone with a centri that installed it will post up

    The beauty of the kit is that it will literally fit anything, you make the hoses.
    So you can route the hoses around blower/turbo/whatever and it will look like custom made hoses because they are. Cobra guys use a Mustang GT lower rad hose but I don't think it will work with Panther radiator.
    Mustang and Panther radiator inlets and outlets are opposite. Otherwise you could use a Cobra/Markviii X-over tube in a MM - but those cars have the inlet on the pass side, outlet on the driver's side. Panther has the inlet on driver's side and outlet on the pass side IIRC

    Awesome, thanks for the responses guys and the link. If I make the change I'll sell my mint cross over tube here on the forums to help a brother out.
