The pawn shop mustang uses the same tuners as the CIJ mustangs, Gotoh GB1. The Hipshot replacement for these are the HB10 model https://hipshotproducts.com/collections/bass-tuning/products/hb10-bass-tuning-machine which can be ordered with lollipop paddles.
A hipshot HB7 lollipop set as fitted to vintera and JMJ mustangs won't fit as they require an 18mm hole where the GB1/HB10 use a 15mm hole.
