IRD Quad Bottom Brackets are made in Japan by Tange Seiki. We carry bottom brackets which work with the cranks we sell, which means JIS square taper (will not fit for Campagnolo). For a replacement bottom bracket on a Long Haul Trucker with the stock Andel crank use the 118. For Sugino XD2-500T crank use the 107. For the Sugino Alpina 2 crank use the 110 to achieve 45.7mm chainline to the middle ring. Call if you are unsure. Also get the crank puller tool and the bottom bracket installation tool if you don't have them.
