Speed 3 seat swap into speed 6

Has anyone tackled putting speed 3 seats into a speed 6?
I know it can be done, but how is the question.

The simplest way I can think of is swapping the entire seat over to the factory speed 6 rails, the rails are a 1/2 inch difference in width.

 

It's been done. Details are lost

 

I figured it out. Wasn't that bad actually.
You just have to dismantle the seats entirely off the frames, and just swap all the cushions over to the factory speed 6 frames, everything lines up but you have to loosen the rails from the car for correct fitting, one bigger point you kinda have to leave the driver seat (motorized) in the car to get the front 2 bolts on the lower cushion

 

A little update on this, when I originally installed my Mazdaspeed seats into my 6 I only ever got 3 bolts in on the driver side, I have fixed this.
Here is how,
I would recommend doing this before you put the bottom cushion on the seat frame.

The driver seat frame rail where the front 2 bolts go through need to be ovaled out, towards the middle of the seat about 1/4 to 1/2 inch on each side, doing this should make the front bolts line up correctly.

The mazdaspeed seats are more bolstered than the stock seats, they are a upgrade from the leather seats for sure, and they go well with the rest of the interior.

 

At some point I will tackle putting the heated seat pads in, as my factory seats had heat and the switches for them are tucked away under the seat for now

I may have to do a better write up of this then.
Airbag light is still very on, have yet to take care of that, I think I'll probably just try one of the airbag defeat kits they sell for the aftermarket steering wheels.
I'll try that and report back on it when I do.
