After reading posts on this topic going back to 2007, I think I posted a picture or two of my use of the VW front hood spring opener, they used on the Beetles, since 1960, there about or a few years later. I did some modification to the spring and it's parts to allow the deck lid to pop up, at a cost of $2.00 in hardware. I pulled the spring assembly off some old junked out VW Bug, sitting in someone's yard, they said was junk and the part was free.
One person wrote they wanted the gas filled struts to push the deck lid open, in case of an engine fire. Well, I hope nobody has an engine fire, but was discussing this "fix" with a friend, who said that is not a good idea as the fire would certainly, in a few seconds wipe out the seals on the hydraulic shock and the deck lid would close. Fire has nothing to burn on my revised VW front hood opener spring. It may not look as clean as the many various gas filled struts I see used by many of the speedster owners, but IF a fire started, I pull the deck lid latch and it will pop up, for me to use the fire extinguisher and not have to hold up the deck lid.
There are no plastic parts on the old VW spring assembly, no fluid , no rubber seals to melt, from the fire. I am into function, not looks. Life span of this old spring assembly ? It was already 45 years old and still works good, so it will outlast my time on this planet. You know, those gas filled struts might last five years, but never 70, as I estimate my old VW spring has in it. Function and long lasting and fire proof.
