I have an older Kelty Tioga (external). The frame has plastic spacers to raise and lower the sholder straps and it has holes in the frame to adjust in or out (left /right) the shoulder straps and lifters. There are several options for adjustment (too many) and I have lost some weight and need to readjust. My last attempt at adjustment did not go well on a weekend trip. I have not seen material on line for this particular pack, The model id is long gone from the tag, It is green, with a larger frame which adjusts length at the top section. Any help would be appreciated. Thanks.
