i think you can get the quaife straight from them for $999,, now the real problem is getting it in the car,, looks like you will need to drop the engine down in order to get the transaxel off of it,, then you need to split the transaxel to get the quaife in where it needs to be, no small task or cheap one, if some one knows a good place to get all of this done in the midwest please post it,, cheers |
