Certain arms transfers would most likely have taken place irregardless of the timelines

For instance the Mexican BDX (4 × 4) APC, which they designated the DNC-2. The BDX (95 of them) were all delivered to Mexico between 1993 and 1994 and most likely would have been supplied irregardless of timeline as they really werent front line vehicles for the Belgians.

As for how the Mexicans go the AMX from the Belgians - keep in mind that the Belgians did have an option to replace the AMX in their inventories, which was the real life and canon AIFV-B and M113 (improved version) - given the fact that the AIFV is much newer and more capable (as was the improved M113) over the AMX vehicles given the V1 timeline (where its still the Cold War and fighting the Russians is a huge concern) they would have continued to procure them and thus taken the much older AMX out of service (assuming that they increase their army size in any way to make use of the older vehicles once they had sufficient numbers of the new ones) - and selling them to Mexico gives the Mexicans the APC's they needed to make the invasion a success without giving the Mexicans a huge amount of new armor, that frankly the units still in the US wouldnt have been able to stop given the dispositions that were in canon

i.e. the 194th and 198th sure as hell would have been needed to stop them and would be in California and Texas and not in Cairo and Memphis if the Mexicans had had a large amount of main battle tanks and not just whatever the Soviets brought with Division Cuba

As for my research and your comments about it - frankly I wont even dignify that by responding

As for the choice of units I have - keep in mind that list is from canon - I personally dont agree with the canon reasoning about the two training armored units never going to Europe - if anything they should have went in 1998 when MilGov was trying to make it look like they could still support the war effort

and given the balance of forces in Europe by 1998 those two training units could have possibly given NATO a decisive advantage if they had shown up intact
