Does anyone know what size these need to be? Online it looks like they're supposed to be 10mm. Can i just use grade 8 bolts, or do I need special bolts? I reason why I ask is that the ones online are all 1.5" long and I think I really only need something that is .5" long or .75" long max.
Stock torque converter? 10m - 1.50 X 15mm (10mm diameter - 1.5 thread per mm thread pitch x 15mm long I would stick with a washer headed bolt & locktite, not a fan of flat washer on torque converters. Make sure bolt won't bottom out on converter!!!
