Ok, I have the HIO360 taken apart to the point I'm ready to split the cases. My local friend/mechanic will probably help me but I'd also like the advice and/or tricks from the engine guys on this forum. I talked to my other friend who has rebuilt a couple O320's and he looked at me with his mouth open saying they just fell apart. OTOH it also seems some are not that way? (I'd go ahead and order the $11K Lycoming tool but it is out of stock....NOT) 
Thanks,
Jack
