Where is the heater core located on a 95 Chevy Monte Carlo Z-34?

the heater core is located under the dash on the right hand side...you have to remove the dash to get at it...costs approximately 600-850 dollars to fix in a garage.....$550. labor costs alone the part is only $112.00 approx. plus coolant and taxes..better off to do it yourself or offer a friend a $200. to change for you!! However, if u have Air conditioning, you have to drain the AC fluid (so i have been told!!)
