George, flipping the RVator pages found this advice:
Aligning Gear Legs [10/94]
There is a fix (to a degree) for those whose gear legs did not come out in alignment when drilled. Even though all kits are now supplied with drilled gear legs, there are still many in the field where the builder must drill his own. In other cases, bent gear legs must be straightened, and it is almost impossible to do this so precisely that the original bolt holes still align when the axles are in the right place.
The answer is AN 385-6 taper pins. To install these pins the gear legs must be aligned properly (even if the original holes no longer line up) and reamed with a Brown and Sharpe #2 reamer (available from Aircraft Spruce). Start the process by using a chain saw file to file the hole in the mount until the entire hole in the leg is open. This of course will leave the hole egg shaped. Use the reamer to open the hole in both the leg and the mount until it is completely round on both ends.
