Yes.
Since my initial post I tried removing the springs from the equation- and most of my fitting problems disappeared.

–- I should have mentioned in my first post that my hinges are repop. –-

About a week ago I posted a piece about a heavy duty ‘53 pickup owned by a friend of mine. (Sighting Network sub forum)
In the course of looking over that nice old survivor I took a close look at the hood springs. They appeared to have less mass than my after market springs, and the resistance to closing was noticeably lighter.

Conclusion: My new springs are too stiff. I think I will contact some boneyards looking for originals.

Thoughts?
