Oil Pan Frustration

Finally got the exhaust and suspension replaced that I removed to replace the pan gasket on my 69 Barracuda 318. Got the car started, oil pressure was good and all appeared well. Then I noticed a significant leak from the front of the pan. It looks like part of that curved rubber gasket got displaced when I reinstalled it. Any remedy to this without taking it all apart again? Frustration level is extremely high at this point.
Only way I can see the rubber seal getting displaced is if one of the locating/securing nubs ripped off while pulling them through and the seal squished out while fitting, simply didn’t see it. Completely understandable considering working underneath things......if in fact a nub ripped off. Agreed, gotta pull and try again
