All, I'm buying my first Ferrari 1999 355 F1 Spider and have two question on Belt Service. I've replaced my Belt in my 928S and understand how to do it and why it needs to be done. My questions: Do many of you in this forum do your own belts and is there any special tools needed (holding flywheel....)? Can this be done with the engine in place? I'm searching the forum for someone who has documented the procedure as well (will be getting a manual soon). Silly questions but want to get it right before tackling the job. Thanks, Boaf
