Adrian
Are the arrows on the pistons or on the rod caps? If on the pistons do
the pistons have half moon cut outs like a dent in the top of the piston?
if they do ( and they are in the right position in the first place) You
are screwd. If they are flat it shouldn't be a problem with rotating them.
I will be corrected.
