When I bought my 66 401 W/ST-400 they had been separated and then stored for some time. The bolts that hold the torque converter could not be located. I have seen used 401/425 ST-400 torque converter bolts for sale on eBay for about $40.00 a set. Are these bolts, or a suitable substitute, available new or will I have to buy used?
They are not a 'normal' bolt. Wider 11/16" hex head and 3/8-16 thread-same for many applications tho-good luck
