If they say XX75 they are the same alloy,I think I have seen them,they are like an autumn orange color.Those old green gamgetters were different shafts,the anodized finish would wear off making the front end silver.If you pull out the uni-bushing I would check first to see if you can find nock adapters for use of glue-on nocks for your size of shaft.I like the uni-bushing system.It makes nock replacement easy and tunable,you can rotate the nock for the best fletching clearence.My favorite nock for them is Easton 3D Super nocks,they have the largest and deepest throat of those types of nocks.And fit my strings just great.
