Jflowers 3/8-8 joint question?

[TrxR]

Anyone know if a JFlowers 3-/8-8 joint will match up to a Radial? It looks like a Radial in the pictures.

They are different.
But....
If you have a standard 3/8x8 tap and tap the radial shaft. The shaft will fit both the radial and the 3/8x8 and vice versa.
Hope this helps.
