thread die for strut rod

I am getting ready to make my own strut rods for a 1969. Where is the most cost effective place to buy a 5/8" 18 thread die left hand thread? That is the correct die is it not?

Moog strut rod nuts for 1967 are K4004. I'm absolutely positive that
the matching die is 11/16-18 because I just looked.
Now for the guess- I'm pretty sure those nuts fit 1967-1973 Mustang
applications, but I'm working from memory and don't have the Moog
book to verify.
McMaster-Carr is where my die was purchased.
The nuts and the die are right hand thread, by the way.

Thanks for the suggestions. I will be turning the current strut rods down to 5/8" following the instructions on Daze's site.

5/8"-18 2645A87 $31.37

A little more than I expected. Plus I would need a die handle. Any additional suggestions?

Got any friends who race dirt track and do their own chassis work? That's who I borrowed mine from. Another choice would be paying them to do the threading for you if you're not really friends.

Alex, are you following any specs or instruction to make your strut rods? I plan to have the suspension out on my '67 vert in a couple months and was thinking about this mod as well. Just looking for the best write-up to work from.

GypsyR, I don't but have been tracking down the parts and alternatively a machine shop nearby.

caveeagle, I am using the writeup from DazeCars, Home Made Mustang Adjustable Strut Rods however, he has changed his page to not include the details. I found an old version at DazeCars, Home Made Mustang Adjustable Strut Rods

It did occur to me as I was pondering this project that the strut rod should not be threaded with left-hand threads but instead with right-hand (common) threads. Can anyone confirm this before I buy the thread die?

They are standard RH threads. If you dont have a die handle, you can get a hex die and use a regular wrench to turn it but they are closer to 50 bucks. I would think you could find a local machine shop to turn the threads for that much.

Thanks for the quick reply. Could have been an expensive mistake if I had bought the incorrect die. I am sure I would have caught that mistake before actually cutting the threads though...well pretty sure.

To make the swedge tube adjustable (without removing) would need reverse threads on one end. right? I think it would be easier to find a reverse thread heim joint and just have your strut rod cut for R-hand threads.

The swedge tubes I've seen come threaded right hand on one end and left handed on the other. So you will need to accomodate the left handed threads one way or another. If you can find a right hand die more cheaply and easily you can indeed just use a left threaded male heim joint as they are available from whomever you get your tubes from and they are priced the same left or right.

What year car are you working on? I did my own strut rods short of cutting the threads. I started to with a die but couldn't keep it straight so I took them to a shop to be milled down and threaded with my die. I bought the die at a local Fastenal store. I think I went with RH and bought the LH threaded heim joint for the front. I went with the closest size to the original strut rod shaft size so I would be needlessly cutting off too much metal. Daze's are for '65-'66 strut rods which I believe are thinner than '67-'70. Mine is a '67 so I went larger with the die, heim and next larger size rod clevis but it looks like according to Daze's site they've stopped making the stronger versions.

I did them on my 66 with a 3/4" die, 3/4" swedged sleeves, and 3/4" left hand thread heims up front. Seemed easier to me than turning down the shaft.

Tweet66, what did you use to mount the front heim joints to the frame?

I actually modified the mount the way Cobra Automotive does by eliminating the center bushing plate (the one with the hole in it). Welded on washers (outside) and a 3/4" through bolt with spacers to center the heim. I then welded a plate over the bottom of the strut mount to box it in and keep road dirt out of direct contact with the heims (see pic).
