I nearly made the same mistake when I got my Tiger Lite. For some reason in my head it was a 6.25u spacebar because I didn't read the layout properly, so luckily I double checked before buying my tx stabs. When I actually got it built PBTfans was nice enough to include the 7u bar in an additional bottom row with the tsangan caps in my neons, which helped me not to forget again lol.
