I have a 110 staggered feed .308 with the side bolt release. Serial#F4993xx. I have lost the safety cross pin somewhere on my shop floor....all I found was dead bugs after a hour with a magnet and flashlight. I have also managed to break the tab that goes into the top of the receiver for the safety. I have looked on the schematics at Numrich but found no side safety models without buying the schematic. What model do I have? And, when you put the cross pin through the side lever receiver and sear, do you have to squeeze down on the assembly to get it to line up? I went to the Savage parts sight and it said that they have no parts for prior to F833xxxx, Mine is after that, what gives? Can I put a whole different trigger assembly on this rifle? not just the SSS or Rifle basic but a Savage one?
