Thanks a bunch for the info. I did try looking for the High Standard part but ran into the same problem with availability. It seems the problem with this lifter is that the tang that lifts the assmbly was a weak spot and it broke on many of these and similar models. I did obtain a lifter from a 12 gauge of the same model and I am currently attempting to get a Gun Smith to modify it to fit. The 12 gauge doesn't attach with the same type of tail/tang.
Again, thanks for the response.
