Here are pics with measurements if anyone wants to help me source these. I will have more pics of all the bearings, part#s, and measurements of all the rest of the bearings within the next few days.

Ok, here is what i have. There is a little bit of pitting, but its not real bad. Definitely in much better shape then the originals you have. If you want them they are yours. You can have them. Just reimburse me for shipping.

That is fantastic! Thank you so much
We'll PM you about the shipping.
Later we will post the photos we have from the mechanic, but if 2869ral is already going to photo all of it, it will just be for fun I guess

The pictures are great Ron. Also, very generous of you in all this.
With the code from one of the pictures NTN 95724, the following is the information I found, that coincide with Ron's pictures
| Inside diameter | 1.25" |
| Outside diameter | 1.875" |
| Width | 1.5" |
| Rollers diameter | 0.3125" |
Needle Bearings (2) needed. Equivalents:
NTN 95724
BAL 200524
BERLISS 95724
Timken J402048
Bower J40 2048
Hyatt 95724
RBC 95724
Rollway 200524

the main shaft could be welded and machined back down to spec. Back in Mississippi, my father owned a welding and machine shop. He had a process where the worn shaft was chucked in a lathe and after heating the shaft a powder was applied that bonded to the metal, and after cooling could be turned back true, and it was good as new, and held up great to wear. i don't know if that would be available where you are or not, but this was 25 or so years ago, that my dad started using this so it has been around for some time. good luck on the repair, and since you are going to be looking for someone to build up the synchronize gears, the machinist might could fix the shaft as well.

I spoke yesterday afternoon with the mechanic in Argentina. He told me that the inside of the counter-gear is in perfect condition. Only the shaft and the needle bearings are needed. He also suggested the possibility of welding and machining the shaft, and then treating it (I assume is heat treatment). At this point I think
2869ral offer is the best solution, since those bearings might prove difficult to find over there. As you can see from the measurements I posted, the needle bearings are in exact standard (inches) measurements, and over there everything is metric, since most of their automotive and heavy equipment looks to Europe.
I also suggested welding the tips of the synchro rings as
robs30m did, but the mechanic has never heard of it. I should add here a comment that
robs30m told me when he did his synchros. He secured the synchro to a piece of steel with the same conical shape as the underneath of the synchro, to keep it from deforming under heat while welding. Robs knows this stuff. If somebody tries to do this without too much care, the synchros could be trashed. Probably Colombia is the only possible source at the moment for new synchros.

I just found these, i will send them as well. They are a little worn, but this is all i have. I hope they work for you.
