Since the other forums on this are mostly talk, I figured I'd post a pic of the Sierras going in. I'll have them the way I like here soon. You can see the just of what I did. The ply in this is really strange and it almost melted of sorts when I cut into it. I'll build my own formers to support these out of 1/8 real ply and support the originals on both sides.The wheels are 5-1/4 Glennis. I'd like to keep as much of the original well if possible. More cutting to come.
