ran into a problem with my zenki conversion

[i4jdm]

so i bought a salvaged zenki for hella cheap cuz the damage was fixable and it had a kouki front end.....long story shot i took the front end and put it on my other 240....now im trying to put my zenki front end back from my original car on the one that origanally had the kouki front so i can sell the car......problem was i didnt take the kouki impacted renforcment off with the conversion........problem now is that it doesnt work with the zenki front end and i really don't want to take apart the cars and switch the parts over cuz its a hours worth of work that i don't want to do agian.......so my question is, is there anyway to make the kouki impact reinforcement work with the zenki front end or am i join to have do all the work over again just for the part.....any input is appreciated!
