Your attitude is a choice, and personally I think yours stinks. I choose not to be like you. For my part, the conversation has ended.

Thanks for the input Lynn.I live up here in the middle of nowhere, north of anywhere, up the armpit of....well you get the idea.My carrier is very much a DIY project. It's been fun and a real challenge, My first vehicle restoration/rehabilitation.BUT, I need the proper tools for certain areas to make life easier.The closest machine shop to me is 108 Kilometers away, and I would'nt take my wheelbarrow to them let alone my precious carrier parts.They have a well deserved reputation for shoddy work.What exactly BSF thread are these long bolts that go through the springs? Like BSF 3/4 x 14 threads to the inch?There is a very nice lady at the local auto shop who really goes above and beyond to help, but I need to know exactly what to ask for. Ditto on the threads that are on the axle shfts for the wheels.I have a friend who lives in lexington , in Mass. But again I need to know exactly what to ask for.There are no gauges locally here that match that thread pitch and count. Any help on info would be appreciated. As for the other comments(ahem!!!!!)I have been to the states many times and met many good people. Since 911, I've been hassled, harassed, and treated like shit by more than a few border guards and customs officials, but thats politics, not life, and thats beaurocracy, best ignored.Out the gate, people are still people.Too bad we MLU ers are so spread out, we could have one hell of a meet and greet!!!

I'm glad we've returned to the original pont of the thread.
Threads, taps and dies.
I assume you've sought out tables of the diameters and threads per inch for the various threading standards. BSF, SAE fine and coarse, whitworth etc are all decribed on the net. Most of the standards are different enough that careful measurement will let you tell which set of threads your example fits into. I would be surprised if there were a metric thread on a carrier so that should narrow the field a bit. Normally for the larger threads like yours I actually count the number of threads in an inch rather than measuring one pitch and taking the inverse, it reduces the number of ways I can get it wrong. Measuring outside to outside on the male thread is usually close, but a bit smaller than the thread size. On Chev CMP trucks I don't recall meeting any bolts that had to be measured to 1/32 inch, I think 1/16 is the smallest step between sizes. Anything is possible but unless there is a special need I think they would have stayed with similar increments as "standard" practice on carriers. Be cautious on how much of what I said above you take as gospel I don't actually have a carrier for experience.

If you google "thread data charts", Go to the one that says just "thread data charts". There is a list that says British fine (BSF) in there under the .750"Dia. (3/4") it says there are 12 tpi (teeth per inch) That is the thread on your spring rods.
Like I say, your axles are a special thread. Measure the dia of the thread, and count the threads or check with a gauge. Then hunt around the various thread charts, until you find what it is. It is a very fine thread for the dia. (it may be something like a "cycle" thread.
As far as basics go the steel in your carrier is in metric sizes, but none of the threads are.
All the other threads are BSF(British) except for the ones in the Ford componentary(engine gear box diff)which are almost all UNF(American)

So all the countersunk screws(flat or round head) in the hull etc are BSF.,the majority of which are 5/16. BSF.,3/8 BSF.,and the screws in the tow eyes, are 7/16 BSF.
All the wheel bearings are metric (6000 series) except the fan extention which are imperial sized. I cannot remember what the one is, at the bottom of the steering column(I think imperial) If I recall correctly the flat Tecalamite grease nipples are also BSF.
As far as you axles go, I would take all the damaged axles, and nuts with me, when visiting your friend, because I think you will be hard pressed to find a set of dies, and a die nut or a tap to suit. They will need to be repaired on a lathe, even better if your friend has a suitable thread chaser.
I Hope that helps, and best of luck with your project.
Maybe you can let us know how you've got on with the various issues you have to work through.
