    Trunk Prop

    Have a janky prop on my trunk lid that makes me cringe when I let the trunk rest on it. It’s off to one side and tweaks the lid. Only a matter of time before she rips out or worse ;(
    I like the gas shock setup but appears that there are several methods to using gas shocks. I’d rather no have to replace my hinges to mount the shocks from the hinges, forward.

    Any suggestion?

    I have the gas shock setup from Factory Five and no complaints. They hold the trunk lid up fine with easy one handed operation.

    This isn't the best demonstration but it does show the cushion effect when closing.

    Where are your shocks?
    Are they mounted to the hinge and forward to the roll bar area?

    Not so sure I can make that configuration work anyways. I plan to install the Breeze Cockpit Storage cubby there in the future and looks like that’d be in conflict.
    I’ve see some online where the gas shocks mount further back inside the lid and go to brackets fit to the tube up underneath near the hinge mounts.
    I’d be interested to hear from anyone that has that setup and their thoughts.
    Perhaps a source for a kit if available.

    I have the Breeze cubby, you have to cut slots in the rear wall for the struts to pass through. Not a huge deal.

    I've done struts with cubby on several cars. As Mike says, easy peasy!

    Nice thanks for sharing.
    Where’d you source the handle on the passenger side of the dash from?

    I think it's this one. Edwardb used it on his roadster build, and several other builders (myself included) then shamelessly copied him.

    Hey Jeff, have you ever installed these on a finished MKIV? No cubby, center mounded battery, not a lot of room for my old fat *** to gain access.

    I always do it with the body off. Not impossible with the body on but like you said not much working room to get at the front ball mounts!

    I got one from amazon. Made some custom steal brackets. It's what I told passengers to hang onto in leu of the windshield. Will put another one in my next car as well. Super useful.

    I’ll be in the same boat doing it body-on eventually. It’s totally doable.

    Thanks for sharing. The Amazon add is a little odd in description but I think that’s the 10” one correct?
    Also, you made brackets? I was wondering if the dash alone could take it. Care to share a pic underneath the dash to show what you did?

    But consider first, whether you want people putting/pulling their weight from your relative thin dash. I’m opting out, despite the fact that it looks amazing.

    I installed one too, and the steel brackets are rock solid and isolate the dash from any stress.

    Agreed
    I had a peak under there last night. Not an issue to make it rock solid.

    Similar setup here, made from angle iron from the local Ace. I have an extra thickness of aluminum as a backer panel for my dash, so I wasn't worried about shear forces on the dash. In / out of plane is handled well by the angle iron behind the dash. Briefly stated: it ain't movin' . Like OB6 said - rock solid, and very reassuring.

    The photo is taken before I had fabbed the second bracket, and before I had drilled and tapped into the top of the 2" square frame member for this one (hence the clamp). But it gives a pretty good idea of what you'll be facing.

    I could not find a handle I liked. Did not want stainless or chrome. Could not find a black one I liked, so I made one and painted it to match other minor accessories in the cockpit. If you install one. Weld in a stout bracket that will take the wieght of the largest person you think will be sitting in that seat!

    I just purchased one as well as the cup holders. Feels like they should be pretty good. Sorry for hijacking the thread.

    I considered getting one and powder coating it. But, really, I don’t want to encourage anyone to put their weight on my dash—they’re not made from very thick material.

    Freight was going to cost me a kidney and a lung to get new hinges shipped to Oz, so modified my existing hinges with some 1/4 inch ally plate and sourced struts to suit. Result: a satisfying arvo in the garage with hand tools, and a trunk (boot) lid that works like a charm. Still plenty of room for a cubby, or battery, or in my case, seat belt retractors.


    gas strut.jpg

    Notes:
    - Drilled and tapped 6mm threads into hinges. Allowing ally plate to be bolted up to hinge.
    - as this was retro fitted, I couldnt rivet the strut ball mount bracket to the chassis of the car. Just got cheap and nasty with some self drilling metal-threads. To be honest, they pull up tighter than a rivet.

    Cheers,

    I did mine with the body on, no-one would call me skinny. Used self drilling screws instead of rivets for the ball mounts. It's a bit easier because the lid is off. Actually, the worst part was realigning the lid, whilst fighting against the gas struts.

    Curious to know what kinda of torque is applied to the connection at the fiberglass.

    Any chance you can send me a picture of the writing on the gas shocks?
    Curious to know lbs of pressure and stroke or model number. I’ll fab this myself too and may already have sufficient gas shocks on the shelf in my shop.

    My kit came with 20 lb. gas shocks for the trunk and they weren't strong enough to hold the lid open, so I replaced them with these 28 lb. shocks:

    https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

    They're still not strong enough to open the lid by themselves but they'll hold the lid open.

    When using the FFR designed hinges and struts ZERO pressure is applied to the fiberglass. The struts act against the hinges.

    Yes, I found a picture. nothing fancy but I used a tap to thread the other end right into the square tube
