The hood spring I made my self I used a stepped expansion plug from the hardware store marked the location of the spring then drilled a 1/4 hole through that area I used a bolt a fender washer through the hood through the plug then the right size washer and nut so when you tightened it expands then found a spring to fit over the plug and a plastic cap to fit over the other end of the spring so you place the spring on the plug tighten the plug that holds the spring the put the cap on and your done costs about 9.00 the second question I'm not sure what you asking I just pulled the spring part of the hinge off then removed the spring and cut a new slot so the springs dident have so much tension just enough to hook the hood up
