I've just finished calling PepBoys, AutoZone, & the foreign car parts places in Nashua, NH trying to locate the glass bodied GBC fuses. All have the colored ceramic bodied ones, Only 1 said they occasionally get glass instead of the ceramic, but they can't control what their warehouse sends. Also haven't had any luck searching the net. Even when I get hits on GBC & 'glass' the detailed description says ceramic. One place told me that BUSS used to always be glass, but they've gone to the ceramic ones also. The BUSS catalog page for 'glass tube' fuses shows the GBC in ceramic & says nothing about glass. Does anyone know of specific mfgs & p/ns for the glass fuses? I need a set & have promised a customer in Shanghai that I'd send him a set.
