No problem, these look very similar to the Powerflex and they do have the large washers on the front set of the bushings, just as Powerflex does. Asthetically the biggest difference between the Powerflex from what I can tell is the rear Powerflex are one piece, and the Powerflex fronts don't have holes drilled in them. So these may be a bit softer or it may be that the holes are to minimize noise and vibration...:shrug
I'm just going to use washers, a 4" pipe, and all thread to remove the stockers. Don't have to worry about destroying them so I may even re-evaluate that after I get a good look at them. These will obviously go in easier than M3 bushings and Powerflex because the rear Powerflex bushings are one piece as well.
