Benito,
The ebay ones works great. Once installed per the instructions, you can do 2 things to improve operations.
1. Tighten the struts all the way down tight by turning strut unit clockwise.
2. Important. Loosen the truck latch screws and adjust the latch position UP near the top of the slot & then retighten the screws. This allows a quicker & more powerful release. If you loosen too much, the truck lid will vibrate. Just play with the adjustments until the vibration leaves & the truck pops.
(3. Replace the trunk lid PADS. The little circular pads wears our & gets thin.. I used high density foam disk 1.5 inches thick with gorilla grip double-sided tape.)
Took me a week of adjusting the truck latch screws, until finally getting the desired performance.
