Tools to cut cf are somewhat expensive. Idk what kind of holders exc. he has but knowing that I might be able to help point you in the right direction.
I wasn't a fan of the stuff I bought. After fucking with them for awhile I did end up getting them to fit. It took some doing though, I don't think I'd buy another set honestly.
Personally, I like to search for what I'm looking for. Once I click on it, I read the description. If I like what I read, I click buy. With a website it makes buying parts a 5 minute process instead of a few days.
