Great idea about the tank. I have salvaged the mounts off of CA95 tanks and transferred them to other tanks, so that's an idea to fit that scrambler tank.
I have always liked the solo seat look, but the CA's just don't lend themselves to a functional spring type seat. I removed the shock mount & post from my donor frame. The pics below show the progress so far.
The seat will be mounted on a separate forward mount. The mounts will be welded. The frame will be sandblasted after the metal work is done.
