got some pics here
the whole hinge setup could work on the inside lip of the trunk, but will definately not work in the same setup as in the pic.
the entire hinge assembly is 2" wide
the lil' baby shocks are 11-3/4" fully extended and the shaft has a travel distance of 3-3/4". possibly more if the hinge is not stopping it.
The lil' baby shocks are 1" wide



I think they can be mounted without the loss of any more room against the side

The box is made by Taylor, the battery cable co, got it at a speed shop that used to be around here. Ran the positive cable along the pass, side and through the firewall. The neg. was grounded in the trunk. We now return you to your regularly scheduled thread.:D

A bracket would have to be made, and side mounted inside.
still a good option to get more room inside the trunk itself.
the space used on the new hinge would be about equal to the hinge already there. just in a different place.

Pretty much the same prinl as the Monte hinge.
I got an idea for a bracket just along the inside of the trunk gasket.
I'll see what I can dream up tomorrow.

I'm working on something that will bolt to the trunk hinges and mount to the back seat.  I've been through about 6 different struts trying to find the right fit.  Still not sure if this latest will work. 

One big concern I have now is that where they mount at the other end won't be strong enough.  Right now I'm using the back seat brace.  That isn't as strong as I imagined.

The problem with  the bars is they are in the way sometimes and you can knock them out of place while hitting them with stuff in the trunk. But I still like them, Old school, reliable , never wear out! I haven't really dug into this but what about mounting the gas thing on the Trunk arm just about where the torsion bar goes in! then find a spot in a straight line from that towards the rear deck and measure to find out how far away with the trunk open and closed. Then how much the lift will you need to hold the trunk lid up. you can get the blade Bolt type lift or the ball stud type.

Just from personal experience with the gas struts...keeping them parallel to the ground when the trunk lid is closed will be the key to a successful design. This puts the gas pressure at rest over a horizontal area, which evenly distributes the pressure laterally. Once you start tilting the angle of the resting strut upward, the struts will consequently start pushing the trunklid upward, causing gaps where water can get in. So...going from the hinge area toward the bottom, back edge of the trunklid itself seems to be the most logical way to do this correctly.

Engineering things on a convertible makes you solve problems a little differently. ;)

Any suggestions on keeping a strut compressed for installation?

Got the struts installed and everything works so far. Is there a "crossed fingers" smiley?

Here are some pics and a parts list, in case someone is interested.  The first two pics show it safety-wired for installation.  The third pic shows the passenger side with the install complete.  There are plenty of strut choices, some have ball studs with them and might be a good choice.  The ball studs I used were sold by a camper supply.  At some point in the future, I might modify the trunk hinge mount by using "T" nuts instead of nylocs.  That would make a nice flush fit.

Parts: 
Mighty Lift 4408 x2
ball stud x4
nyloc nut x4
bolt x2
nut x2
washer x4
angle bracket, cut to fit x2
3/16 fender washer x4 (get grade 8 if possible)
safety wire
zip ties
's' hook or similar
