Axel and gear box gears.HO 44 tonner

[steve turner]

Guys i have a bag of replacement gears for 44 tonner, they are white.I believe i purchased them when i originally had the two motor 44 tonner.Do these gears fit any other 44 tonners. I have units with SQUARE top brass gear housing and the ROUND top brass gear housing.I did note at least three different truck versions on parts department list but only one diagram. Curious to know if the gears work on each truck or any of them?.Thanks Steve
