Ultimate seat with OME drivers backrest??

[alycatmcclurg]

Hi:
I just bought an Ultimate seat for my 2016 F3 L. I had the OEM backrest on it already and from the description on the Webpage for Ultimate it says it works with all Can am backrests. I am having an issue with getting it into the seat and don't want to jam it in. Anyone else have this issue? Do I need to buy the backrest from Ultimate?

Thanks

I have the ultimate backrest from lamonsters. Feels much nicer than brp's. You wont need the mounting bracket since your is built into the seat. Just the slide in arm and pad. Don't know why yours wont slide in.
