a lot of people bitch about it not fitting in the housing so for anyone replacing their heater core in the near future here is what u need to know
first of all the core is a little different

as u can see the tanks are different but it will fit
thats the hole behind the glove box where it goes
see its in the hole
any ways what you have to do is get the tubes started out the firewall then shove up and in on the bottom and then push the tubes threw
like so then you can do like me and take the piece of cardboard that came with the core and fold it so you can hold the core and push the hoses on...
having 2 people makes it easier but i like to work alone plus no one was here
after all that tighten your hoses and install the cover back on the box then the glove box....
i drained my radiator and sort of flushed it with the water hose till everything ran out clear... and refilled with anti-freeze and some water then started it let it warm up and finished filling the system ....... check for leaks
