I am looking to do my first zed build and am trying to put together a soft budget before I get too deep (1972 240z). I have budgeted out most of the guts, but am having trouble finding the particulars on the body I am looking for. I love the look of the two body's below but can't seem to find the correct air dam or flares? I believe another post had the air dam as an IMSA 3 piece but do they fit with the flares I want? Also, I am new to body work and do not know how wide these flares are. My questions are... What type of air dam are these? What type and size are the fender flares? Will the air dam fit properly with the fender flares as shown in the picture? Sorry if these questions seem simple, I just don't want to spend money where it isn't needed and get the right parts the first time around. Thank you!
