Is that a filler between the rad. support and the rad. ? looks like ur rad. aint mounted right in the pic , it should be up tite against the cradle or dang close.
Like I said in the post you quoted, the radiator is pushed all the way forwards.
The end tanks are thicker than the radiator core leaving a small gap between the radiator support and the radiator core. I have speed tape covering any gaps.
