Is it harder than the 87-93 dashes. I have removed many 87-93, but never a 86. I have to replace my heater core. thanks

 

PRETTY MUCH A DAYS WORTH OF WORK
I HAVE NOT YET DONE THE 87 UPS BUT THE 86 BACK TOO MANY TIMES...................

 

If my memory serves me correct, I think you can get at the heater core through the glovebox, once you remove it, but my mechanic told me it was a pain in the *** to do it that way. My shop manual said you can do it that way too...

I'm sure though
