Dear Joel L

Thank you for your inquiry.

P90 Dog Ear pickups are generally mounted directly to the guitar body using wood screws.

Please find the links below to check the screws and related items required for this installation:

1. Pickup Cushion : Used for height adjustment of the pickup and to ensure proper contact with the guitar body.
