No glides
I don't believe they ever had glides. If you look at old Herman Miller catalogs, the IT-1 does not appear to have glides and I've never seen an example at auction with glides.
Here are a half dozen examples, none have glides.

According...
To Eames Office, there were glides. Maybe they were poorly designed and fell off. That's why I'm wonder if the other ones will work, if the original glides for your table were also the screw-in type.

more questions about my ITM
My Itm is a little different than my dtm in that the legs are not removable. My dtm has a pin that can be pushed through the wood to remove the leg. My Itm only has on hole so it is pushed in to place, and can not be removed. Is this common to these tables? Thanks

ALL THESE PARTS ARE AVAILABLE!
Visit www.mancha.demon.co.uk or try searching on Google. You will find all of these are available. Graham Mancha, the guy who runs the site seems to know quite a bit about the furniture. He's actually super helpful and def knows his stuff. Can supply items that I've had a real hard time finding in the past.

IT not DTM
I think there may be some confusion here. The DTM is the dining table with folding legs. The IT table is the same design, only smaller to be used as either a child's table or an incidental table (hence the IT designation). The Eames website gives a date of 1948 for the IT and 1949 for the DTM, but the Eames Design book says that the entire group was designed in 1947. I think the DTM tables had a screw in glide until 1953 when they switched to the same style boot glide as the DCM.
Again, I do not think that the IT had a glide at all. The table they show on the Eames website does not have any, every photograph I've ever seen of the design does not show glides, and the IT table I own does not show any signs of ever having had any sort of glide at all. No hole in the bottom of the leg and no halo from a small boot glide as you often see when they are missing from vintage DCMs. I can take photos that show what I'm talking about.
Seems like a small point to quibble over, and of course if we are talking about a DTM rather than an IT table, the point is moot. The DTM of course had a glide. However it seems as though rozellglass has both forms and knows the difference. Regarding the question of leg construction, I have never seen an IT table with a configuration different than that of the DTM. That is, with the pin that allows the leg to fold but remain attached to the table top.

One
of the wright20 listings does have glides or feet, but it is hard to tell what they look like and whether or not they are original.

Original?
I could be totally wrong, but I doubt those feet are original. They look to me like the kind of plastic feet you can buy at the hardware store. Again, if you look at the vintage photo on the two page spread on pg 82-83 of the Eames Design book (the double exposed picture with Charles in the room twice) you can see pretty clearly that there are no glides on the IT but there are on the DTM, LCM, DCM, and CTM.
Here are images of our IT table with a detail shot of the feet and a size comparison next to a LTR.

Pegboard
I do believe you.
Just out of curiousity, I wonder if the standard LCM/DCM boot glides would fit or are the legs a different diameter?

Unfortunately no.
The legs of the IT table are much more slender than the DCM or LCM legs.
