OK I KNOW SOMEONE HAS INFO ON THIS. I HAVE A 84 REGAL AND I WANT TO INSTALL LINEAR ACTUATORS ON THE TRUNK TO RAISE AND LOWER IT AND HAVE IT STILL LATCH OF AT LEAST SEAL DOWN SOME HOW. I WANT A NICE CLEAN INSTALL ON THIS. ANYONE DONE IT? I ALSO HEARD THAT A CONVERTABLE TOP PUMP ON CYLINDER SETUP MAY WORK BETTER THEN A LINEAR ACTUATOR, IT MAKES SENSE TO ME BECAUSE YOU CAN PUSH ON EACH SIDE OF THE TRUNK AND GET EVEN FLOW TO EACH SIDE BUT WOULD IT BE FAST ENOUGH? PLEASE HELP!!!!!! :uh: :cool:

I would design the system and use a latch assembly out of a later model Caddy or Lincoln that when you closed the trunk the latch assembly grabbed the lid and motorized it down tight against the seals. Some of the early 90’s Camaro’s and Firebirds had a similar type latch setup too I believe. I used to hate those because they would pinch your fingers if you were not careful.
I would also design the system to where the trunk lid is counter balanced. What I mean by this is you want the actuator or lift mechanism to work the least amount it has to. If the lid is not counter balanced the actuator or lift has to move all of the trunk lids weight. If there is a counter balance incorporated into the design it might only take 5 pounds of force to move the lid open and shut. Without the counter balance you would have to use something that has maybe 100 pounds of force. If you have ever had a trunk lid that the counter balance springs or gas shocks have failed then you know how heavy the trunk lid can be to open when trying to open it at the farthest point away from the hinges. Try and lift that same lid being closer to the hinges and it takes even more muscle.
Use mechanical advantage to your benefit. An actuator with 5 pounds of force can through levers and things give out 50 pounds of force but at a cost.
However you design it make it to where if the system does fail or come out of adjustment you can get the trunk open to repair things with the least amount of damage or none at all.

I HAVE ALREADY THOUGHT OF ALL OF THAT. I WAS GONNA LEAVE THE SPRINGS IN THERE TO HELP LIFT IT. AND I THOUGHT OF THE CADILLAC PULL DOWN, ALL MY LLACS HAVE THEM, BUT THE PROBLEM THAT I SEE IS WHAT IF IT RELATCHES BEFORE I GET THE TRUNK UP? IT WILL LATCH AND THE ACTUATOR WILL BEND MY DECK LID IN HALF, LOL. I THOUGHT ABOUT PUTTING A ON/OFF SWITCH ON IT SO THAT I COULD KEEP THE LATCH FROM GOING UP UNTILL I WANT IT TO GO UP. I KNOW THAT MOST LINEAR ACTUATORS ARE PRETTY STRONG AT LEAST THE ONES I HAVE LOOKED AT AND I PERSONALLY WOULD RATHER DESTROY THE ACTUATOR THEN MY DECK LID BUT THATS JUST ME. THANKS FOR THE HELP! ANYBODY ELSE HAVE THEORYS? THIS ONE GOES RIGHT ALONG WITH MINE!
