Help with K frame

Somebody please help me. I picked up a 75 Dart sport last year and stripped it down as an organ donor. I took the front disc brakes, k frame and 8 3/4 rear. I'm finally ready to get started. Washed my k frame down to discover that the spool mounts were cut off and relocated 3/4 " back. I believe this is the correct direct connection modification to mount a B R/B engine. So now, my dilemma, am I screwed? do I have to cut and weld back to the original position? Can I mount the motor mounts on the front side of the ears? Does somebody close wanna swap frames? I am so pissed at myself for not catching it sooner.:banghead: I wanna get going here soon as the weather is just so darn beautiful. Thanks in advance for any help or guidance y'all might shed on this.
