Classic/Antique Car Repair: help....frustrated 66 chevelle heater core replacement, heater core replacement, water hoses

Question
Having trouble accessing the heater core in my 66 chevelle. I have managed to remove most of the bolts that attach the cover to the fire wall. however there seems to be one bolt high in the fender I can,t get at or find for that matter. Any helpful tips would be appreciated, thanks

HI I know they are a pain in the butt- you must use real small tools, and I have even seen where some people had cut a hole in the fender to get the bolts out. the best way is to remove the glove box inside. than you will have lots more room- note do not twist off the two water hoses on the heater core or the new one, put a drop of wd-40 or lube so you can posh the hoses on if you try to twist or force them you will -SNAP the ends right OFF $$$
