Recap of my Hinge springs to Struts conversion
Lists all the parts and methods.
I attached to the hinge and let the bottom hang fully extended with the hood all the way up. Marked and drilled to attach the bottom. Yes I just guessed on length. It worked out for me.
14 and 15 inch struts but only mounted for 15 inch. That's what the the threaded rod was for... to lengthen the 14" struts to fit my holes for 15" struts...
