Finished the fwd turtle back. I do have to drill and rivet the support for the VHF antenna. Not exactly as smooth as I would like, but not going to take it off and shim it. Most of it will be under the canopy. On the engine got one of the cylinder barrels off. Drilled the piston head to ease up the pressure. I believe another one is loosening up. That one has a crack. I don't know how that can crack, the guy said the engine was running when he removed it from the car, but could not have been running with two cylinders cracked, I don't think.
