1967 Fastback trunk Torsion Rod
« on: March 03, 2020, 11:48:27 PM »
I can't seem to find the replacement torsion rod for fastbacks anywhere. I see the two piece set for coupes and convertibles, but not fastbacks. Anyone know where I can find one? thanks.

Your going to need to post WANTED ads on this site and others like VMF (lots of members most focused on other than stock/factory cars) possible SAAC site and so on

Or find someone that still has a yard.

No easy button for some of these things.

Good luck with the search

I have a spare clip that I know where it is and I think I kept the spare rod I had. I am in a condo until I figure out if I am staying here, or going to be based out of KPHL.
I'll let you know. If you need the center retainer I know exactly where it is.

Thanks Keith. I just got the car delivered yesterday. I have the center retainer and the drivers side rubber bumper. The torsion rod is correctly in place, but trunk won't stay up. Possible rod or hinges? Did you find the extra fast back torsion rod? Thanks

I have had some luck in adding some extra tension to a set of rods for a coupe. Since your rod is weak you really have nothing to loose in trying to add some tension.  I clamped one end of the rod to my work bench then with the other end hanging over the edge a few inches I put on of my large wood clamps on the free end. I noted the existing angle. I also covered the rod with a scrap of carpet and some weight in case the rod broke. I then started twisting in the correct direction to add torque. I would go a bit then back off and recheck the angle to see if I was changing it. I must stress be careful and go a little bit at a time.
Then check it in the car.

Good luck and be safe.

Marty, was that for a regular coupe trunk lid or GT/CS - HCS? My torsion springs won't hold up my GT/CS lid.

Scott it was for a regular coupe but should work for a GTCS as well.

Question have your springs been out of the car? If so be sure that they are not reversed. that will cause the trunk lid the not stay up even on the tightest setting.

Also I would suggest if you are going to work on the coupe springs that you make the removal/ initiation tool shown in the service manual. It makes it a much safer operation.

I have the tool for the double rod set up for 1967 coupes and convertibles. Fast back whole different set up. Is there a different tool?

Not that I'm aware of other than normal hand tools and a little careful application

If I were to try and make such a tool I think I would start with a heavy but somewhat small diameter tube/pipe and slot the end on one side for maybe 3 or so inches so that the end is exposed to insert in the arm once in place. Like the factory did - an extra rubber donut on the drivers side end (to hold the rod into the drivers side hinge) keeps it in place while you wrestle with the passenger end

From my dead seas scrolls file:
The text is dated 12/21/2014. As I have 65 and 66 Fastbacks, I don't know if it will work on later years. But it gives you an idea of what and how.
Jim
The text is repeated here:
Trunk Torsion Rod

Want to load the trunk hinge torsion bars in 30 seconds without broken knuckles?
The torsion bar should be in the position shown in Image #2 when ready for loading. Cut a piece of 3/4" square steel tubing 8 1/2" long. Drill a 5/16" hole about 2 3/8" from the end (image #3). Place the tit on the torsion bar into the 5/16" tool hole. The end of the tool is leveraged under the horizontal bar. Lay in the trunk, and rotate the tool in the direction shown in Image #1.
BOOM - done.

There is a new tool available.   :)  You only need a 3/8" breaker bar or ratchet.

Any pictures of how its used for a fastback? 65-67 fastback rods are basically all the same but coupe/convertible pictures as well as the instructions you included don't look like they would explain how it's applied for this application

Thanks

That doesn't look like it would work on a fastback. If you slotted the hole you might be above to get it out of the way and you slide the end into the arm - if not its just in the way once you get the rod aligned I would think
