A little while ago I did the same modification on a Universal Hobbies 1/18 MGB GT, the problem I noticed
on that model was its rear quarter panel, the opening seems larger than Autoart's model
Look at the last 2 pictures to see the difference
modifications:
Lowered Front and rear suspension, minilite wheels, racing decals, racing seat, roll bar
Before
After
