cowling that supports the gas tank

[k24556]

OK Need some help. I would like (I think) to take the front cowling off the car; the one that supports the gas tank. The few reference books I have do not mention how to do this, and it looks like there may be some rivets to grind out. Since I am in a no harm mode, i.e., no bolts or rivets were harmed in the filming of this episode....... I thought i would ask the experts.

Body goes to the soda blaster as soon as I get that cowling off.

What is the secret?

Also, engine comes out tomorrow and heads to the machine shop. It is currently 1/8 over, but the cylinders and pistons are in remarkable shape.
