What I hope you have or are willing to get is the sam's and a diddle stick (a small PLASTIC* hex key). *If you use a metal one you are likely to crack the slug, and it is harder to adjust since the metal acts like part of the slug, and once you pull it out your adjustment will be off.
You need to adjust the horizontal osc slug to dial in the hold...You see the front H hold pot on most sets is a fine hold control, the coarse hold being the slug(s) adjustment. Don't just randomly adjust it, follow the sam's procedure since there is the potential of damaging the fly if it is badly out of adjustment.

I'm reading the Sams under misc Adjustment - Horz Sweep circuits.. It's telling me to connect a 0-500ma meter to in series with cathode lead of Horz Output Tube and .47 mfd cap across the meter.. Then it says to connect a 0-1500 meter in series with the cathode lead of HV regulator tube.. Then tells me to adjust some controls and one being the horz osc control and some measurements.. At this point I'm already thrown completely off.. It does say to adjust the horz adjustment on the TV set control to the middle.. So that I'm aware of.. When I looked under the set where the 6j56 horz output tube is, i saw metal jumpers under the tube socket that connects to different pins.. looks like that would need to be unsoldered to connect amp meter in series.
I could either let Dave take over from here and restore the set, or attempt myself.. I've gotten this far.. Looking at the old coil, the slug is adjusted way down into the coil verses this new one, so I could either adjust the slug on the new coil to around where the old one is, then turn the set on, and slightly adjust right/left until I lock horz in.. Or I could be walked through on where to connect the meter.. Which I'm not expecting anyone on here too..
