What service kit do i need?

[Bowers]

It has come time to service a sherwood blizzard second stage that was breathing hard so i left sitting on a shelf. I’ve tried adjusting it but it goes from breathing hard to freeflow and nothing in between, and my ip is correct with no creep.
It’s one of the smaller ones before they made the pro. Right now i just need a kit for the second stage because i wont be needing the first stage for the foreseeable future, as i have swapped it out for a used din style of another brand.
Anyone know what kit i need and where i can find it? I don't want to accidentally order a kit for the newer style and find out it won’t work.

If you don't see what you need, call them.

You might just need this Low Pressure Regulator Seat - Medium - Fits Most Regs and a few o-rings.
