There is no doubt it is a RUG trans. But the input shaft being 1 1/16 10 spline and the output being 28 spline, is telling me it is for a small block ford, but as i said in my other post some big blocks had the 28 spline output also most was 31 but some did run the 28 spline, if i remember correct they were in 64/65 Galaxy .
