Main bearing cap broken how to repair

My feelings I would not run it the way it is. Simply it is broken and needs repaired or replaced. If it was mine, I would replaced the cap with a new one OR a used one, and take the necessary steps to insure a proper fit. I would braze it, if I could no longer get the part, or if the car is going down the road for good. The oil pump nipple and shaft must be inline with the bushing and distributor shaft or you may have early failure. The opening has been created now, you have a hole, oil pools in this area to help lubricate the lower part of the distributor shaft and upper part of the oil pimp it self. I would not sleep at night knowing this broke, take the extra...and fix it.
