I used a similar set-up but mounted it to the decklid itself on one end and to the channel that's right along the edge of the trunk on the quarter panel for the other end. Sorry I do not have a photo. But when closed, the "ram" lays parallel with the edge of the trunk opening and does not take up any trunk space. It did force me to remove one of the trunk hinge rods. When I'd hit the power trunk release, the decklid would fly completely open!!
I'm thinking that the ram wouldn't have enough leverage to hold open the lid if it was mounted to the hinge. That is why badcatt has his going down to the floor. It's all in the angles and geometry, you know, something that not everyone is great at. I'm one of those people.
Hey Cowboy, I added an Eliminator style spoiler to the decklid of my 68 where there wasn't one before. At first the spring rods were strong enough to hold the decklid open. But, they quickly became weaker and I needed to do something to help support it. I believe (but don't quote me) that real eliminators had a prop rod from the factory to cure this problem, like those that hold up the hoods on some of the cars that don't have springs on their hinges. Badcatt and I as well as others here went a different route and are using a gas charged "ram" type of device like those used on a hatchback to help hold the decklid up. Hope this helps the explanation a little.
I bought one on ebay from Cutco. Now I'm now way a novice when it comes to cars and what not. I couldn't figure out how to mount the stupid thing to save my life. So I sent an email to the owner telling him to send me an installation sheet. He said no problem. 4-6 weeks later after many emails to this nut, I never seen any instructions. I left him not negative, but neutral feedback on ebay. He finally emailed me back telling me to get F***ed and that I'd never see any instructions now. Some customer service policy they have there a Cutco Industries. I never ended up installed it.
Hey Vfret - I contacted Cutco after purchasing mine from them and I did get a reply. In a nutshell it said "I just reproduce and sell these things. I have no idea how it installs. I suggest you find someone with te part installed and see how they did it." DUH!
I haven't put mine on yet, I am hoping to get a picture of one with correct placement at a show, but I did ask on the forums where it goes. Here's the thread: http://www.mercurycougar.net/forums/showthread.php?s=&threadid=3693
When I got in touch with Cutco about shipping to the UK, said they could but I really got the impression that they couldn't care less. Wasn't very impressed and I also queried how they mount. I was told the same as Rktmn. I am going to try a prop rod from a mini. They are plentiful here and about the right length. They are used on a mini to hold the hood up. Failing that it will be a gas strut from a hatchback from the local breakers.
