True about the Super Bee drop top. The box art on the kit lists and R/T version, and R/T ragtops were available in '68.
I don't remember if this kit can be built as an R/T, or not, it's been 50 years since I've seen one of these kits! LOL
I was partial to the Jo-Han flat box kits from days gone by. Especially the ones that had customizing parts in them. I have several flatbox kits in the stash. Hafta be careful with them....they don't stack very well!!
That's the way mine did, too. Looks like Revell missed it a little bit, there. I didn't bother putting putty on mine, as I had already painted the piece.
