Brake Master Cylinder P/N cross- reference

[rupertjl]

I just won some NOS Brake Master Cylinders on Ebay that the guy claims is for an L-19, so I have the Goodyear p/n of 9521626, is there anyway to find out if it's cross-referenced or the same p/n as what on figure 24, page 42 of the 170A parts manual. ( 0441019 and 0441019-1). If not, I can use them on my homebuilt, but these look like the same ones I have in the 170. OF course I'll know for sure once I get them, just trying to do a little preplanning.

v/r,
Jud
