yes, last march i did exactly that. my cobra is a daily driver and i drive it hard. but this radiator now has over 8k miles on it with no problems whatsoever.
i did a full write up about it at the time. i did a lot of research but there were no truly bolt in replacement options available for the stock unit.
I run the LMR SVE radiator, fit fine, much bigger than stock too. I had to slightly bend the ac lines to get it in there, but that was it.
I have a used GT radiator I bough years ago from MPS and never used. I'll sell ya that one for $50+ the ride. It is much smaller than a stock cobra radiator fyi.
