Assuming you know how to strip down and later re-assemble your own bikes...
Seriously consider bringing the frame and fork in two separate pieces to a shop with serious alignment equip - or a frame builder for a work over. You are going to do a rebuild anyway, right?
Steel bikes including Pinarello's can take alot. I've seen a Pinarello Model "Twisted Sister" visit my local frame builder...and depart 2 weeks later as a Pinarello Model "Heaven's Door".
