hi, I recently purchased some off ebay for my build. They have listings with different lengths and force (nm if metric). I found some that have the ability to adjust the force. i.e. let the gas out, with a supplied allen key. I didn't want the bonnet and boot lid to fly up when opened. They were only about $29 (AUS) a pair. If you get these, make sure you let the gas out only a smidgen at a time. Once it's out you can't put it back.
