I later discovered that the GTO's wheelbase is a little long (maybe 1/16th of an inch, nothing too serious) for the MDT chassis and the '55 CHevy (now back out of production), '69 Camaro Z-28, and '70 Mustang Mach 1 would probably be a closer fit. I'll post my initial findings on the bow-ties later on, but the Goat and maybe the Stang would be a better choice if you want a little easier go at it. Revell also makes a C3 Vette ans was making a '34 Ford 3 window coupe, but the Vetter would probably be best for any Monster Garage recreations, and I don't know how well the '34 body would be for a Jalopy body and it's been taken back out of production again too(if Mike still has one at Naperville I pick it up on Sunday.....)
Here's the pics after attacking the Goat with a Dremel




After this mock up I ordered the Baja front tower/rear body post set and a set of Street Meats. Gotta love how cheap this truck is to modify...even whe you get carried away
