anyone knows where to buy 1986 chevy chevvete online?

where to find this stuff online for a good price ?

Have you tried www.autozone.com

You should just go to a local auto parts store or junk yard and save some money on shipping.

This is a good place to start if you're in Canada or the USA.

can i use chevy chevette heater core year 84/85/87 instead of 1986?

The same heater core is used on all of them from the late 70s to the late 80s. Really *any* heater core will work, just chevette's are a favorite due to their small size and good performace. I'm using one off a 87 (I think) Chevy Truck cuz it's bigger and can fit it. My suggestion (what I did) is to find a used car part store / junk yard and go through their pile of heater cores untill you find the largest one you can fit in your case.
