How do i remove the A pillar trim?
Do i just snap it off as i don't see any screws holding it in place.
Any sweet spots where i should start pulling it off from?

They just pop out. Start up top and slide down. It's the damn b and c that I can't get at. Seatbelts are annoying. I'm too much of a ***** to unbolt seatbelts.

getting the B off is the easy bit, its getting it abck on thasts the bloody fiddly bit, especially after they have been trimmed in material, as it snags trying to slot it together

piece of pizz for the a pillar put a flathead screwdriver at the top an turn the screwdriver ,as for the b pillar remove the top cap[flatheadf underneath it] then it will expose a bolt [should be 1/4 inch ]un do that and repeat the same as the a pillar
and finally the c pillar, take the bottom seat seat out undo the seat belt bolt and put your fingertips at the top of the pilar and pull[gently forward]
then feed the seatbelt through it
