two envisionings tonight. Hmm... spellchk doesn't like that
First.. where to put the reservoir

need to make a hole

here it will be

then onto the radiator - more specifically, the air intake

move it 30* then it works just fine

still don't know what air cleaner, so this is back in play - my first C3 Corvette had this for an air cleaner because, even though it was a SBC, hood clearance was an issue.
the first C3 I ground up built - and, since it's story time, it's the car I bought the flares for but couldn't convince myself to cut it up to put on the flares.... dumb dumb dumb dumb - except this car would eat that one's lunch - it had all the bolt ons that Optima seems so enamored with..... *shrug*
