It would REALLY nice if they redid the whole chassis with inner fenders and an actual 351 Cleveland and 429CJ engine (not a 302 and 428). As they have not made any changes to these molds in decades, I'm not holding my breath. The Boss 351 kit was a joke - no 351 engine - just some decals.
I noticed looking back at my two builds of this kit that the chrome grille should actually only be chrome on the outer edge and the rest body color except of course for the grille itself. I build these two GT500's many years ago but recently went back to correct the oversight.
Welcome and check out the Midnight Modelers down your way in Stafford. I'm at the Northernmost point of Virginia about ten miles west of DC. I try to go to the MAMA meetings every month in Greenbelt which is about 20 miles from me. Rex
Sorry - I only have the one set that includes the E12, E13, and E15. It's going to be a challenge to find a kit to part out. If I understand what you are saying the parts to build a correct Revell #98 66 Daytona GT40 you need the parts from the 67 Daytona MKII Fujumi version.
I bought one too and will also need another interior tub and boot as I started my own 67 Mustang GT convertible conversion but could not come up with a good interior. Good thing he sells the parts separately upon request.
Norm is always coming out with new stuff so his catalog is probably out of date by the time you get it. I'd suggest you call him - tell him what you're building and I'm sure he can tell you what he has. Check out this Fotki link from Craig Stansfield for some of his products.
