Need help with quick jack hardware - what is this?
Wanting to replicate the original quick jack mounting hardware. Appears that the the bolt head was inside the body (or was it threaded rod?) and the nut was visible when looking at the quick jack. The end of the bolt (or rod) was slotted for a screwdriver. Here's a pic I found from what appears to be an original 427 car.

The nut is an Aerotight all metal locking nut. Came from the British aircraft industry but used throughout original Cobra's and Cobra 427. They are available still through current suppliers. Just Google "Aerotight" nut and you'll find them.
I'm not sure about the slotted shaft but I think Acton Custom sells them. Larry |
On the subject of Aerotights, does anyone have a source for 7/16" UNF? I can get most other sizes, but not fine thread 7/16".

Have you tried fastenright.com? They have a pretty big selection of nuts.

Yes it's 3021 and that hardware came from moi.

Just put them on my Hi-Tech this week...thanks, Nick. I slotted the rods with a Dremel.
btw, Nick...you said it could be "tricky" to get up behind the brake air scoops. That was understatement :-) But I'm very pleased with the result...the details do make a difference. Bill |

I need your help to confirm/correct my understanding.
The mounting hardware available from Acton was used on 427 Comp cars and NOT on the 289 race cars. On all pictures I checked on 289’s I can see only “normal” bolts and not the mechanical locking nuts. :confused: http://www.clubcobra.com/forums/pict...ictureid=17003 http://www.clubcobra.com/forums/pict...ictureid=17004 |
I would expect American made NAS specification bolts and matching nylon insert prevailing torque self locking nuts for any period Shelby American installation.
