A/T vs. M/T counterweights?

I've got a rebuilt engine out of an automatic car that I'm dropping in my manual car. People have told me I need to change the front counterweight, which made sense at the time. So in anticipation of pulling the front plate, I went to order the gasket from Mazdatrix. But if you look here, Mazdatrix lists one counterweight for all S4 cars. I'd really rather not take anything apart that I don't have to, so does anyone know if there's a difference between the auto and manual counterweights in an S4? Thanks.

Sorry misinterpreted the question. As far as I know, the front counterweights should be the same. Maybe someone else can verfiy this.

The front counterweight is the same. Its the rear that is different. On an auto car , there is a counterweight that bolts onto the eccentric shaft(like the flywheel does) and then the flexplate bolts to the counterweight. On the manual cars, the flywheel has the counterweight built in and no external counterweight is used.
