TRW Piston Specs

[basstrix]

Do any of you have or know where I can download old TRW specs? Looking for catalog data for L-2379F pistons that were commonly used in 351c.

Conversely, if any of you know for certain that the Speed Pro numbers have remained unchanged in comparison to the old TRW numbers.
