Hi Tgraham,

The bridge post inserts are a tight fit as they are held in place by friction.

Normally, on a solid body kit I hammer them in with a block of wood between the hammer and the insert. I'm not sure I would want to do this with a hollow body.

With the FH kit, I assume there must be a solid block of wood under the top where the posts go. Can you insert a clamp through the bridge pickup cavity and below the block? Then you could use the clamp to force the post into the hole!
