I contacted MH about some decals and never heard back from them and so did another member on decals he needed.
Cub Cadet customer service is worthless and their tech support isn't much better. They don't make parts for older machines like Deere does because they are in the throw away lawn tractor business now.
If you have an existing decal you can take to a local decal place and have them make you some. I had a guy that did that for a 3240 and he sold me some that he had made.
Contact this seller and see if he can make you a set for the 3235.

This is the only other decal I found.
