I wanna switch from HIC to SCS. Although I have 26h heptrons with a slit. If I blocked the Slit with a piece of standard Bars jammed in to cover the slit would this be trustworthy? I don't wanna pull a Tom K.
Yeah, you should be fine. Make sure the block you make for the slit is an extra 1/2" to 1" than the length of the slit to be on the safe side. And if you don't like how tall your bars are after SCS cut like a 1/2" off the bars and it'll be even safer.
