PT wing attach bolts

'It finally happened - the engine lost power, batch of oil hit the right wing leading edge, and so engine was shut down.
There was a farmer's dirt strip a short distance off so pilot restarted and nursed enough power to make a dead stick landing. Pilot and airplane all okay (other than the engine). Oil pressure had not dropped.

Bore scope in #5 cylinder showed that piston does not move when crankshaft is turned. Guess is that piston must have separated. Have located rebuilt cylinder, piston, valves, etc., etc. My mechanic would prefer to not make an in-field cylinder replacement to fly the plane home (about 5 miles away).
Have figured out most of what is needed to move the airplane to my hangar. But this will require removing the wings.
My question is: What is the best way to remove the 8 wing attach bolts?
Mounting the wings turned into a major project due to the VERY tight fit of the bolts. Is removing them going to require the same 'big hammer' technique?

'Yes, but having done the same thing you are doing, twice, it wasn't that big of a deal.  For the record, once was due to the airplane being damged by some else taxiing into it, the other following a forced landing.
In the latter case we even separated the center section from the fuselage, but if you don't mind the wide load on the trailer with the center section attached, that's the way to go.

Just have the proper size drift and back up on the other side.
