Hood hinge repair or replacement

Mount the struts with the cylinder above allows the seals to stay lubed and last longer.

I started with 150 lb. each struts and are currently 200 lb. each.
I plan to put some sound deadening and an insulation pad that will add a little more weight plus paint and turn signal wiring and hood latch and fasteners... 200 lb. seems good now. I have identified 220 lb. alternates just in case.
The 200 lb. open nice when cold or hot. 180 lb. seemed to get a little weaker in the cold. I also assume they weaken a little over time...
I don't want the hood to be open and a little breeze to accidentally shut it on me or anyone else.
