Welcome to BikeForums. If you know the length and offset of your old bottom bracket spindles, there are manufacturers of cartridge bottom brackets other than Shimano that offer more details. Search a bit, you can find tables for the Tange LN-3922/7922 bottom brackets, as well as the IRD QB-xx models. Good luck!
