Why don't you want to use the 10X19X5?

FLM originally did their mount with the 8X16X5 but changed to the 10X19X5.

When this came up I did calcs on the bearing volume (as a quantitative way to compare size). The original 10X15X4 has a volume of .392 CC, the 8X16X5 has a volume of .753 CC, but the 10X19X5 has a volume of 1.02 CC (CC - cubic centimeter).

So the 10X19X5 is 33% bigger ((1.02 / .753 * 100) - 100) than the 8X16X5. Plus, if you use the 10X19X5 you only have to modify one part and everything else remains standard, stock, and easily replaceable.
