Anyone know where i can get a flexible seat belt buckle that will fit through one of the side holes in a fixed bucket seat to allow the waist part of the seatbelt to restrain me tightly? I have purchased a few different types but i can’t find one that the S13 seat belt will fix into. A seat belt extender would work as i could run a bolt through the male side but i can’t find one for a S13.
The stock buckle being a fixed metal type runs next to my seat rather than through the hole so it doesn’t grip me tightly.
