As of now the nose to body fit has been holding me up in moving forward in a timely fashion but.....this is a holy grail build of mine so I'll be taking my time with this one.
All of these AMT Mustang kits of this year model ( Fastback, GT-350 and the GT-500) have the exact same problem with the nose to body fit, particularly on the drivers side. A little TLC is all that's needed to fix the problem.
This is the NASTY join on the drivers side of the car:
Sanding the front edge of the drivers side fender ALL THE WAY down from the top of the fender where the side contour of the fender is to the bottom helped the gap throught the top an d bottom edges of the fender/ nose seam. Once that was straightened out I noticed that there was a slight interference fit issue behind the headlight on the no se piece so I took a small file and trued the area where the headlight bucket meets the leading edge of the fender called out as area #1 in the photo below. After that I trimmed out the area behind the headlight called out as area #2 in the same photo. These couple of mods seemed to help things out alot.
another thing that I did that seemed to help was that I used the back side of my X-Acto knife to carve out some of the "meat" out from the drivers side front fender where the backside of the headlight bucket meets the fender from the inside as pointed out here:
Although the passenger side doesn't seem to have the alignment & fit issues that the drivers side does you can see the difference of what I had to cut down on the drivers side as compared to the same area shown here untouched that's on the passenger side.
I'm still working through this issue some but I'm getting closer to the point that I can use a little filler in the gaps and sand it down some. You can see that the top of the headlight bucket is now flush with the fender at the top joint and the sides have a cleaner join between the nose piece and the fender all the way down the sides.
This one area of the build is a true challenge to overcome but a little "lovin'" straightens it all out.
