Crosman 1322 o-ring/pump seal kit

Hey all! New member from Canada here.
So I have an old model 1322, think it's a mark 1 or 2(has "crosman arms" on piston tube)
Having trouble finding parts, have even talked to a crosman Representative on phone, to no avail...
I'm hoping someone here knows something about it. Such as, do they exist/are the newer model's seal kits interchangeable?
Thanks in advance!
Cheers from Canada, happy plinking!
