88 90 heater core

[THOMAS TAUSKEY]

Dave:

Still haven't done heater core on mine --but go to Alex's site for a comprehensive description of this job

http://surf.to/the80pages.com

I haven't yet got the replacement core and pose this additional question to the list .....

While it seems that the heater core element is fairly readily available, are there significant differences between replacement products?   Put another way, how come these heater
cores seem to fail so often?   What component manufacturer's product (cores) are to be avoided?
