In April, the Z28 returned. Perhaps Chevy finally saw the success of the Trans Am and wanted back into the game. The Z28 had a wide multi-color hood decal, wheel opening, body sill, and rear spoiler accent stripes available in four different colors. The bumpers were now painted to match the car as were the wheels which got a new centercap emblem. Click here for a scan of some 1977 Z28 factory literature. With the Z28, came the Borg Warner 4 speed. California emission Z28s were not available with manual transmissions. 1977 OPTIONS #MADE AK1 Belts, color keyed 64,923 AN6 Adjustable seat back 12,528 AU3 Power locks 20,173 A01 Tinted glass on all windows 181,982 A02 Tinted windshield only 4,475 A31 Power Windows 31,028 B37 Floor mats front and rear 86,144 B80 Roof drip moldings 66,021 B84 Body side molding 133,738 B93 Door edge guard 59,100 CD4 Intermittent wipers 16,190 C24 Hideaway wipers 16,190 C50 Rear window defroster 73,242 C60 Air conditioning 144,767 D35 Sport mirrors 109,520 D55 Center floor console 207,926 D80 Front & rear spoiler 46,103 F41 Performance suspension 27,079 G80 Positraction 18,095 G92 High altitude rear axle 750 J50 Power brakes 193,889 K05 Engine block heater 4,851 K30 Cruise control 25,100 LG3 Engine 305-145hp 2bbl V8 147,173 LM1 Engine 350-170hp 4bbl V8 40,291 L22 Engine 250-105hp 1bbl I6 31,389 M15 3 speed 8,810 M20 4 speed 8,423 M21 4 speed-Z28 (Borg Warner) 5,114 M40 Turbo hydramatic 196,507 NA6 High Alt. emission 4,374 N33 Tilt steering 77,491 N65 Space saver spare 22,643 PE1 Turbine wheel 20,015 PO1 Wheel cover 21,444 QBT FR78-14 tires white letter 34,928 QDV FR78-14 tires blackwall 13,263 QDW FR78-14 white stripe tires 142,141 QEG E78-14 tires blackwall 2,511 QEH E78-14 tires white stripe 11,656 QRZ GR70-15 radial tires white letter 14,350 T59 Conventional battery 17,972 UA1 Heavy duty battery 14,607 UM1 AM radio with stereo tape 12,881 UM2 AM-FM radio with stereo tape 17,353 U05 Dual horns 16,653 U14 Special instrumentation (guage package) 12,877 U35 Clock 26,340 U58 AM-FM stereo radio 21,128 U63 AM radio 68,795 U69 AM-FM radio 33,166 U76 Windshield antenna (included with radios) 58,293 U80 Rear seat speaker 27,430 V01 Heavy duty radiator 17,720 V30 Bumper guards 49,576 YF5 Calif. emission 24,088 ZJ7 Rally wheel 87,481 ZJ9 Auxiliary lighting (ash,hood,trunk,glove,courtesy) 42,837 Z21 Style trim group 93,706 Z49 Mandatory Canadian base equipment modifications 18,433 Z54 Interior decor group 25,328 Z85 Rally Sport 17,026 1977 COLORS Exterior Interior 11 Antique white 18,19 Black 13 Silver 11 White w/black 19 Black 02 White w/blue 22 Light blue 24 Blue 29 Dark blue 17,72 Firethorn w/black 36 Firethorn 71 Firethorn 38 Aqua 62 Buckskin w/black 44 Medium green 03 White w/aqua 51 Bright yellow 07 White w/firethorn 61 Light buckskin 06 White w/saddle 63 Buckskin 64 Buckskin w/saddle 69 Brown 75 Light red Z28 Stripe (codes=?)
