Pella Designer Series Sash Locks

Our house has Pella Designer Series Double Hung windows that were installed in mid '90s to early '00s. There are two different style of sash locks (pictures attached) One has #45105 and the other has #45254 on the underside of the lock. Both styles showing either deformation or cam wear. Looking to find a direct replacement, or one that can be retrofitted. (I have proficient mechanical/woodworking skills) Can you help?

Turns out one of my windows has a sash lock that looks like a 90-243 AND it looks like it would be a drop in replacement for the ones I have that are in the attached photo. It also looks like the strike is a bit beefier and is less likely to bend.
