Newbie to Forums.. Taper and Tie Rod Ends.. Need help building a draglink.

I have a Draglink with two different size Tie Rod ends on it..
The tie Rods are crimped on both ends.. (No unscrewing the Tie Rod Ends for replacement).. It is easy enough to rebuild it once I find the correct Tie Rod Ends..

I would like to find the largest thread diameter SAE or Metric and fit threaded ends into the round tubing, so, I can replace the tie rod ends down the road.

Right now, the Tie Rod Ends have aprox 1" diameter or Metric equivalent that would go into the new tie rod adjusting sleeves.. But, considering they are crimped, I don't even know if they have threads yet. I have not cut open the draglink yet.
Planning on using Tie Rod Ends and Tie Rod adjusting sleeves to remanufacture the 41" drag link..

I am having a really hard time getting the taper data on existing ball joints out there on the market.. I know I have to get the taper correct to get started..

Anyone have any suggestions how to get lists of that kind of data so I can match them up?

Any help would be much appreciated..
If I have posted in the wrong area, I would be happy to post elsewhere.
Thanks.

Thank you.. Sorry.. I don't have enough posts to put pictures/links, at least on the first post. I had to delete the link to post it. When I deleted the link, I deleted the paragraph describing it..

This is the message I get:
To be able to post links or images your post count must be greater. You currently have posts. Please remove links from your message, then you will be able to submit your post.
Let me see if I can get around that for a minute to let you see this.

It is a 1984 Ford 3910 4WD tractor.. 48hp.

Right now, the front ball joint is bad. Popped out of it's socket.. Rear is Ok, but, would like to fix both and put it back on there.. I can't see any way to fix the current tie rod end that could be expected to last.. I figure, cut the old one out or off, get the correct size tube and weld in one end of a Tie Rod adjusting sleeve and screw the tie rod in to the correct length. I can cut/fit/weld, etc...

If you notice,, the Tie Rod ends are Hydraulic Pressed into the steel steering tube..
So, there is no unscrewing the Tie Rod end and screwing another in..

No problem though.. I can do it.. I just need to figure out how to get the correct taper and fit on the tie rod end to get started..
Here is the pictures:

You will have to delete the spaces..

I have calipers and use them a good bit, but, not a machinist.
I also have the telescoping "T"'s which are designed to measure inside holes with a 1" micrometer, which should tell me exactly what I have, but, no matter how many times I measure it, the measurements vary..

I have measured the front Tie Rod Taper and the Hole the tie rod slips into..
The Front Steering Plate with the tapered hole:
------
Minimum Taper Size =.665 v
Max Taper Size = .717 v
TAPER Length = .705"
I think this measurement is pretty close.
I guess the reason this works, or should work if my measurements are right is the larger diameter (Max) taper below.
------
The Tie Rod End
It is a 14mm thread with 1.5mm pitch.
The taper measurements, I came up with two different measurements consistently..
Taper:
Min Taper Size: 0.665" and 0.644 0.021 difference in the two mins
Max Taper Size:0.740" and 0.724 0.016 difference in the two max measurements.
Taper length = 0.70"
------
Seems you would have to have the taper length to get close to this.. Which is where the problem lies.. The only place I can find taper lengths is on sites like this one.. An article here and one there with a few part numbers on it.
I can find the mins and maxes for lots of Mogul Part numbers, but, no Taper lengths, unless I am totally missing it here:
htt p:/ / fme-cat.com/PartSpecification.aspx?Brand=MC&prodCat=TIE%20RODS #

I found these specs here:
Mogul ES2010R Min=0.664, Max=0.773 and taper length 0.808..
The 0.664 is right where it needs to be, but, I have my doubts about 0.773 matching up with 0.724" or 0.740" That is + or - a 1/32 up to a 1/6 on Metal to Metal contacts..

This is not my cup of tea.. Any suggestions, directions, comments?
