the ones hidden in the side of the quarters are tricky (pull trim off and you can see it)
but I had a bastard of a time getting the 4 from inside on the floor out as they were as tight as a motherf*&k. Luckily my interior is stripped as i ended up getting a 5 foot pole on the end of a cross wrench with 2 of my mates holding it in position while i practiced my rowing skills from inside
It must have been tightened with an air wrench coz of the respray..
