This makes me think those links are not for your chain which you fail to specify. Spur or rim drive? Only the distance between drive links is standard,. Tie strap and cutter holes and pin space is 1 value. Hole space in drive link seperate value. Manufacturer can make up their own or copy one existing combination. There is an up and down to the pieces. Hole in drive link and pivot pin on preset vary in diameter.
There are joining links on eBay that say applicable for multiple brand and code I find different in spacing and pin diameter.
The Upstart .325 chain copies the Oregon code letter labeling but not the Oregon splicing parts for that product. There are multiple splicing part choices in Oregon .325 for various chain code,. Even if limited to 0.050 gauge.
