For my '82 Z28:

C5 front brakes...done. What a PITA. Box got damaged during shipping, so the adaptor bracket got damaged, had to wait for a replacement, bolts fell out of box during shipping, had to wait for replacements. Took a lot of shopping to find a 12mm allen socket and avoid shipping $$, but Shaeffer's hardware in Dover came through.

Front springs and ball joints...done. Went back to my Moog 5662 minus 1/2 coil springs, pulled out the GM CDB minus 1/2 coil pieces I put in after the LS1 swap. The Moogs are stiffer, understeered a bit w/ 255-50R16 Goodyear track slicks so they were shelved. This year I'm upgrading to 275-40R17 tires and don't have room for the nosedive the CDB springs allowed.

Comp roller rocker trunnions...done. Sent my stock LS1 rockers off, came back w/ Comp upgraded trunnions installed. Measured pushrod length, found my 7.400" rods weren't long enough to put proper preload on my lifters. 7.4500" would have been too long, so 7.425" were ordered and installed.

Injector cleaning and flow-matching...done. Sent my 28# LS1 injectors off for ultrasonic cleaning and flowing, put the highest-flowing ones on cylinders 5,7,8 and matched up the rest by cylinder bank. Probably sell my SVO 30# injectors, they ran nice but the stock ones are large enough to stay below 85% duty cycle.

High-beam indicator on dash...not started yet. My electronic speedo has no provision for a high-beam indicator, got pulled last Fall for failing to dim lights for oncoming traffic. Written warning only, but a PITA so I'll be adding some sort of indicator light.
