there are seven bolts in the dash, but have to take 2 bolts out that hold the fuse box plus 4 nuts that hold the steering column up and you can pull back the dash enough to get at the heater box and there 3 or 4 bolts that hold it in. then you can see 4 bolts on top of the heater core housing that you can take out. oh don't for get to disconnect the a/c hoses on the firewall and the bracket there are 2 nuts be careful. i did my wife's heater core in her 87 t-bird last week. if need pictures i have them okay at

in order to remove a heater core, you must take apart the whole dash. when i tookout my heater core in my cougar i had a hard time and i cut the dash and later on i founf out that you take it all apart. that's all i know. Dustin from pa

What helped me the most was this website, it practically walked me through every step. Be careful with the dash, mine was very fragile and i came close to cracking it many times in this process. good luck!
