For the s2 at least plenty of room to pull out.
I better let that one go through to the keeper . . .
BDA , So on a tc you don’t have all the clearance that’s in the picture? If I recall correctly it’s about a 6” bolt , I have at least all that before
Got a pic with the bolt removed, Dave?
My stock bolt is 4-1/2 inches long. To get it out, you'd need that 4-1/2" plus the thickness of the bolt head.
It's difficult to judge but going by your excellent pic and given the boss through the trailing arm is 2-1/4", Im still thinking you haven't got the room.
I'd love to be wrong.
