I am sorry, but my skills are limited when adding photos. I have added to my album a method I us for tow line attachments. The Daytona's quick lift jack points lends it self to attachment points like I have pictured with out destroying the use of the quick jacks. The quick jacks were welded on the original Daytona's chassis. The one point you have to address is the distance between the yellow attaching circle on the front jack and the attaching piece that holds the front on. You must allow enough clearance so that the front end can rotate freely.

Default More on Quick Jack Hardware

I pulled my Quick Jacks off last night just to see the quality of the hardware, with an eye towards whipping up something like 1795 did. I was also thinking about adding an aesthetically pleasing folding tow hook to the top bolt of the quick jack. The threaded rod, of which there are two per quick jack, appear to be standard, general purpose, low carbon steel Grainger type stuff, in 3/8". There are hex nuts and washers on the threaded rods behind the frame mounts and there are acorn nuts on the threaded rods in front of the jack pads. It appears to be general purpose stuff. Now, even the weakest, low carbon steel, 3/8" threaded rods have a safe carrying weight of 600 lbs. The quick jacks themselves are thick, heavy steel. If you ran a synthetic web sling, through and behind both quick jacks (four fastening rods), in a basket hitch formation, wouldn't it be significantly stronger than a tow hook attached to one single threaded rod and fasteners that were all upgraded to Grade 5 or even Grade 8? A simple 1" x 8' web sling like this easily holds over 3000 lbs. and would take ten seconds to fish behind the quick jacks. https://www.e-rigging.com/1-inch-X-8-foot-Web-Sling

Patrick,

That should work fine. I did upgrade my bolts to Grade 8 to be sure that they could handle the task. Had to have a tow strap/hook permanently mounted for racing, otherwise I would have just looped something through as well.

Yours is a simple solution that you can carry in the boot for emergency purposes. I wolud suggest upgrading the bolts and just painting the heads to match the quick jack.

Jim

I was going to mount a folding tow hook directly above the quick jack, that caught my eye, but it was actually going to require a decent bit of fabrication to look clean and proper. Here's the hook that I like:

These are nice tow rings. I have the chrome bumpers on my ERA...how
could I mount one of those without punching holes in the body. I needed
a ride on a flatbed last year and a ring would have may it easier to be
winched aboard.

You would want to mount a 90° Tow Hook receiver behind the bumpers right up against the rod that is coming out from the front of the car (and that presumably is mounted to the frame). Then one of those nice Tow Hooks then screws down in to the receiver itself. The E81-4 RennLine looked to be pretty close to what is needed as a receiver, but the holes would have to modified as they do not line up perfectly with the rods that come out from the frame. That would not be terribly hard. Then you just have to make sure that the thread matches up. That particular receiver is 5/8-11 and the E19.209 Folding Tow Hook looks great. Here are the part numbers and below that is a pic of the Tow Hook Receiver and Folding Tow Hook together. Just imagine it mounted vertical instead of horizontal, as seen in the pic. There are other ways to fab it up, but that's how I would probably do it.

E19.209
Rennline Folding Tow Hook - REV2
Universal Screw for use with Universal 5/8-11 Thread

E81-4
Rennline Universal Screw in Tow Hook Receiver
Bolt On 90° Adjustable 1-4"

THANKS for taking the time to respond. I looked at the pictures you posted. It looks like your Coupe is a Gen 1 or 2. I got the general idea how you installed them. Since I don't yet have the car and it will be a Gen 3, I might have to wait until I get the car built to the point where I can see how I could fab them, especially in the front.

BTW the car looks beautiful. It is along the line of what my vision for mine is.

THANKS AGAIN Gary
