This lift strut allows the trunk lid to go up completely. It does not fly up, but rather goes up at a nice rate. It also closes nice, and it minimizes the chances of the lid slamming shut.

I used one strut for a stock trunk without spoiler, and two for a stock trunk with a factory spoiler.

You will need the following parts for one lift strut installation.

1. Lift strut - Ford part number is F4ZZ-63406A10-B and is from a 1994 Mustang GT.
Cost: $20.67 with member discount

2. Ball mount bracket - McMaster Carr part #9512K91 (Qty. 1) Cost: $1.20

3. Coupling Nut- McMaster Carr part #93355A105 (Qty.) 8mm x 1.25 pitch x 1 1/2" lg.
Cost: $2.87

Note: I use the NJ branch of McMaster Carr, phone 1-732-329-3200

4. Pan head screw - #10-24 unc x 1" lg, with hex nut.

To install:

1. Screw the coupling onto the existing stud, as shown in photo

2. Attached ball socket fitting included with lift strut, to other end of coupling.

3. Enlarge top right hole to 1/4" dia. in ball mount bracket, to fit around trunk torsion arm.

4. Place ball mount bracket in position shown in photo, and drill a 3/16" dia. hole thru trunk arm, to line up with top left hole in ball mount bracket.

5. De-burr both sides of hole in trunk arm, and install pan head screw.

6. Attach lift strut to both ball sockets.

You could have used the existing nubs, I did not add any extra hardware and it works just fine. Nice write up though.

So I'm guessing this is in lieu of the factory lift, or if the factory lift doesn't work any more.

My 97 has a nice factory lift, almost too nice, the trunk flies fully open! Brenda's old 96 Cougar, I think it lifted a little bit. My old 95 had nothing at all, or it was broken. The worst part of that is it's easy to slam the trunk shut if you don't know about it, which sucks.

My 95 has just a spring bar and when you unlock the trunk just unlocks but doesn’t move. I have a factory spoiler on order so I’m getting ready for the extra weight. I only installed 1 (so far). When I had an SC as a Fomoco sales car in 1990 I don’t remember what the “new” trunk action was ....

You know you can adjust the tension of the torsion bars for the trunk hinges, right? It sounds like your '97 needs to be backed off a bit, and your old '95 needed to be adjusted up.

No, I didn't know about it. The 97 is fine, I don't mind. The 95, I don't have any more,

This thread stopped short,
I'm waiting to find out how to adjust my 1995 Cougar trunk lid. It has spoiler and falls down.

The tension rods? See the notches that the rods are set in? With the lid all the way up and supported, move the rods to the next tighter notch.
