Need to know correct parts to order

Hello, Kenneth. Looks like you need an all new hinge assembly. The track base and sash frame arms actually all come in one kit. My top recommendation is the 36-048 kit. While the design is slightly different from your original, it will still work as long as you make sure to replace the top and bottom at the same time. That will ensure an even and steady operation despite the differences in design. The video below will go into more detail.
