Sorry it's been a while everyone. I decided Easter Sunday would be a great day to have a heart-attack, followed by a quintuple bypass and two weeks in the ICU. In the ensuing weeks I have slowly started to regain strength, and have only just started back with little jobs on the P15 Club Coupe. I had removed the plugs and been soaking the cylinders in ATF/Acetone mixture, and then spent some silly money at Coker (what the hell, I'm alive), and at least now I can roll my coupe (have to give her a name yet) in and out of the storage unit. I got the wheels powder-coated (extremely close to body color), and had them triple pin-striped in cream. I spent several hours on each hubcap, polishing then hand-lettering them in red enamel, and she now has new ribbed trim-rings too.
That was all from the last couple weeks. Today, I bought a new battery and satisfied my own curiosity that the engine was not stuck. She didn't come with keys of any kind - so I had to jump the mechanical solenoid to get her to crank. Just pushing the starter button did nothing, so I am guessing the wiring is such that the ignition key has to be on before the starter button will actuate?
No cracks in the steering wheel, and the DeLuxe horn ring is intact!
