Hey Dean, I didn't actually look at your picture full size the first time around and missed the 'front' marking, so I thought you were calling the right front cyl #4.
So now that I see what you're talking about here's what I remember. Two of the cylinders are oriented such that the pin goes in the slot, the other two are oriented such that it butts up against the other side of the block that has the slot. As I recall the ones where you're pushing the screwdriver such that it generates a counter-clockwise force (1 & 4) butt up against the block, the ones with clockwise force (2 & 3) the pin goes in the slot.
the cylinder orientation I'm using is:
2 1
4 3
What I was commenting on before is my #1 cylinder seemed to not quite rotate to the same angle I remembered it being at upon disassembly, but I was able to just barely get a screwdriver in there and tighten it down. The picture John posted looks pretty similar to what I was seeing on #1, you can just barely get at it, but when I loosened it I didn't remember it being that close for access. But it was a week or so in between the removal and replacement waiting for parts, so I may have just forgot. I thought your problem was you couldn't get that clamp to align such that you could get the screwdriver on it, so my previous reply was regarding that, not the #4 cyl question you were asking, sorry for any confusion.
