Thanks Steve. I first had the separate the grille from the valance, the 1/24 scale kit has them molded as one piece. Then sectioned the grille in between the headlights at both ends to reduce the length. Then reshaped it to fit the grille opening on the 1/25 scale body. For the valance I had to remove a section, its molded integral to the body and graft in a section of the 1/24 scale part. Then worked it to shape. Definitely not a drop in parts swap.
