Thanks, Isaac
I agree that the undercarriage track is quite narrow but maybe similar to the F-104's. On the other way, as you point out, a thrust loss on one engine at take-off or landing would be a problem! The same goes for the F-104, but not for the same reason
The jet engine assembly to the wing was trouble free. There are small fillets at the wing trailing edge. They have a simple shape and are easy to apply.
