Aluminum material question 2024-T3 vs 2024-T351 (wing strut ends)

[Fly Alaska]

After machining the strut ends, I realized I was using 2024-T351 temper, instead of the T3 temper called for. Any metal gurus out there that can tell me if that is ok or not? Looking at the properties listed for the two tempers, they are very close (mostly identical) - but there are just a few subtle differences. Do I need order new material and start over??

I would call Bob and ask him for a definitive answer, but my take would be that they are ok.

The material can be 2024-T3 or T4 according to the drawing. Here are the comparisons in graph form...pretty dang close:
