I built this kit many years ago as the # 17 H&M nascar race car. To make the front fit better I removed the front radiator wall. attached the Tally front, puddied and sanded, then reinstalled the radiator wall. I'm not the best at body work but this turned out to be my best effort, ever, at the time. You could probably just split the radiator core support. It moved the front apart about 1/16" .
