Converting Superglide kingpin box to standard type

Superglide capture plates come in 2 version: Universal and Custom

Universal usually ends up needing welding to complete installation
Custom by design are typically held in place with set screws.....made to fit specific king pin box


Is this plate fully welded in place or tack welded in sections.

Tacked welded can be removed using cutoff wheel in grinder
Plate just slips over existing king pin plate

If fully seamed welded........replace box....easier
