Today's progress report:
King pin kits from East Cost Gear Supply. Fast shipping - 2 days!
Spent 40 minutes with a blasting cabinet this morning.
Dry-fit for dim confirmation before long side cut.
King pin and lower race installed. Caster set. Ready for welding.
Comparison. Photo trickery makes "old" look much longer. Only ~1.5" shorter.
Temporarily home. Link brackets next. Never mind that leaf spring hanger...
