Have not seen many of those for sale. I have seen more of the Gunze Hi-Tech kit, which kind of surprises me, due to the cost. But with Lindberg re-releasing the Jag D type, maybe we might see the Cobra soon too.
If om617 does not have one for you, I have one. Not sure of the best way to ship it though. I usually try to cover them in the same type of tissue that Revell is now using and then seal it in a ziploc bag, but I have only shipped here in the States, so I don't know if this method will cause issues. If Tommy doesn't have it, and if you have any more knowledge about shipping, let me know,
I too happen to think a convertible would sell very well since there have been so many hatchbacks done and we now have the LX from Revell. Just my opinion, but I think it might be worth the time for Greg to reconsider, while the LX is being done and keeping everyone's mind on that era Mustangs
