Sorry to say that these are the same as all modern translations, they all use the same two older manuscripts.
This claim is false and very easy to disprove. Here is page 58 from
Novum Testamentum Graece Nestle–Aland 27 edition.
Notice the heading:
Consistently Cited Witnesses in the Gospel. Clearly there are more than 2 manuscripts listed.
1Jn 5:7 Trinity verse totally omitted. "For there are Three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these Three are One." The passage isn't in any modern versions except NIV, which about 20 years ago decided to include it; but NIV still follows the two old corrupted manuscripts that they all follow.
That's because it is not found in the Majority text. The following list is more than 2 as you have falsely claim. It is missing from the vast majority Byzantine manuscripts. It is missing the following manuscripts.

What happen to your claim we ought to follow the Majority text, the Byzantine manuscripts? When you found out that 1 John 5:7 is missing from the Majority\Byzantine text you dropped that claim quickly.
“
Unequal weights are an abomination to the Lord, and false scales are not good” (Proverbs 20:23).
The truth is you don't follow the Majority\Byzantine text. The evidence shows you will reject the Majority\Byzantine text whenever it does not conform to what you want the Greek text to read.
By the way, there are other verses and phrase missing from the Majority\Byzantine text. I can provide others.
