Mine was an 1-1/4" back, so not too bad, but at the limits of the travel in the slot. I just fought with all four of those screws. 3 fought the good fight and finally came out. The 4th is going to have to be drilled after the head failed. I'm glad I got into this. Two of the bolts were bent before I started messing with them, which I will take as not a good thing. It would be tempting to drill this out for larger bolts, but not knowing what is buried in there I think that is a risky plan. The casting is dirty, but generally ok. I was kind of thinking that under the SS bolt heads there was going to be some serious corrosion, but that does not seem to be the case.
Another trip to the hardware store for another cobalt drill bit.
