A 68X103 BB should fit just fine on this frame right? Rear 120mm - using a Sugino GLP Crank - 130mm Spider.... My first track frame - always made conversions... Stoked on this frame!

I can't speak to that frame, but I use a 68x103 BB with my Sugino GLP. (Actually 144 BCD.)
The thing to watch out for is that if the cranks have been installed and removed a few times in their past, the NDS crank may sit very close to the BB shell and may even contact it, forcing you to use a longer BB.

those cranks need a 116 spindle. since they are road cranks youre converting to a singlespeed, a 103 will probably cause the crank spider to hit the frame.

Thanks, I'm just sitting on a Dura Ace 68x103 BB that i hope does the trick so it finally gets some use, think this build will be pretty simple, just hope that BB does the trick and finally gets some use, it spins so smooth....

Your cog is slipping.
Step two: Measure your chainline (from the center of your BB shell to the chainring). If it's less than 42mm, calculate how many mm you need to add to bring it right around 42mm. Multiply that number by two, add it to 103 and that is the correct spindle length you need.
