I just purchased a 1990 ZR1 with 20k miles last weekend and will be picking it up and trailering home in a couple weeks. I'll have a few days to go through everything on it and then have a 600 mile trip planned. The previous owner has had the car for 8 years and only put 2k miles on it. He recently had fluids changed, but I noted he had it completed by a local oil change shop and would feel more comfortable knowing first hand what fluids were in the car. I'm planning the below maintenance based on recommendations browsing through the various ZR1 info sources, is there anything additional I should check or complete?

Oil Change - Driven HR3 10w30 and Wix filter
Trans Fluid - Castrol Supercar 10w60
Diff Fluid - Valvoline 75w90 Synthetic + ACDelco limited slip additive
Spark Plugs - ACDelco 41-602 gapped to 0.035"
Air filter
Fuel Filter
Replace brake and master cylinder hydraulic fluid (syringe method)
Clean PCV and throttle body
Check brakes

We'll of course do a good 50 mile spirited drive to verify everything seems to be in proper working order prior to setting out for the longer drive.
