Dexter designed the # K71-652-00 EZ Flex as a direct replacement for the 013-104 equalizer.
If you didn't want to use that, the Lippert Equa-Flex # LC279687 should be close enough in height.

To get the correct replacement leaf springs I'll need you to verify the weight capacity of your axles and then take the weight off of the springs by lifting the trailer frame, and measuring the length of the leaf spring (center-eye to center-eye).
Something like the 26" Long 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles # e22YR could work for your application but we'll need to verify the things I mentioned above prior to making a purchase. view full answer...
Lock assemblies can be different sizes and still use the same latch cutout sizes. The Global Link RV Entry Door Locking Latch Kit with Keyed Alike Option - White # 295-000021 will fit into latch cutouts that are between 2-1/2" wide x 3-1/2" tall and cutouts 3" wide x 4" tall. You will need to access the cutout to see if this will fit for not. We do not carry other sizes at this time. view full answer...
