Al Glidewell is pretty swamped with work and I don't think he'll be able to do the scans.------------ Here's a synopsis of the C and D 240-Z mods: for best economy,a rear spoiler of aluminum sheet,about 8-inches ( 200mm ) angled up at 30-degrees gave best MPG for downforce ( 110-lbs ) and 0.20 mpg.------------ The front air dam allowed 3.6-inches of ground clearance,hung basically straight down,canceled 85-pounds of lift and added 0.8mpg at 70mph.-------- The G-Nose,offered on Nissan's 240ZG,with grille block.added length,and covered headlights allowed a 1.2mpg improvement at 70.top speed 5-mph higher and 95-pound lift reduction.Headlight covers by themselves were good for 0.2 mpg.Total for C and D mods: 1.2 mpg @ 70-mpg,from 22 mpg,to around 23.5.
