Is there such a thing as a "95" convertible GT Cobra ?

They produced a Hardtop convertible is that what you are referring to?

It is not a hard top .

Yes they built 1003 cobra convertibles in 1995 according to wikipedia... Ford re-introduced the Cobra in mid-1994 featuring the new styling as well as larger brakes, a revised suspension setup and wider wheels than the outgoing version, a "GT-40" lower intake and Cobra specific upper intake as well as GT-40 cast iron heads. Power was boosted to 240 hp (180 kW). New colors were introduced: Rio Red, Crystal White, and Black. Differences between GT and Cobra included the front bumper (Cobras feature round fog lights), Cobra-specific wheels, and in 1994 and 1995 the Cobra utilized the stock Mustang hood, LX (V-6 3.8L) 'MUSTANG' rear bumper, while the 'COBRA' rear bumper, and Cobra-specific hood with larger "air inlets" didn't appear until 1996. Unique for the 1995 Cobra was the removable hard top option, 499 of the 1003 convertibles built had this feature. These models were essentially the same as the convertible Cobra but had several small provisions to accept the retaining mechanisms of the fiberglass top and dome/map light wiring. The 1994-95 Cobra's rear spoiler was different from the LX and GT, the third brake light was in the spoiler and not in the trunk lid.
