for belts - gates or dayco.. i had a cheapo autozone valucraft belt break on me only after 5 months that almost left me stranded!
power steering fluid - any atf fluid, dexron type
brake fluid - dot 3 type+
oil and filters - whatever's on sale or cheapest... don't bother spending $10 for an oil filter or $50+ for synthetic oil for a freakin '80s toyota 4 banger truck motor.. this isn't a fancy high performance DOHC V8 racing motor redlining at 9k rpms, and youre just wasting money otherwise IMO.
