I am in the process of rebuilding an old GT Talera and have run into a problem. I need to know what size bottom bracket to get but am not able to measure it. Does anyone know where to find informaion on older GT bicycles? (Pre-Pacific Bicycles) I think the model I have is a 96 or 97.

According to my research, the 1996 GT Talera came with a Shimano BB-CT91 in 73mm with a 122.5mm spindle length.
