Yeah, those bolts and nuts will be a bear to get removed after being on the car for 30+ years. Lots of penetrating fluid and a little heat from a torch should make them a bit easier to remove.
A mechanic friend is coming on Tuesday to help removing the old header (hopefully without breaking more stuff !). At least nothing important broke.

I've also ordered a bunch of gaskets, a set of new studs, a new oxygen sensor (pretty sure the current one is original seeing how black of carbon it was !) and a brand new catalyzer from Rockauto.

Next week is going to be packed 😄

WD40 is not that good at penetrating oil on rusted nuts and bolts.
Kroil and BlasterPB are much better at it.

And as mentionned above, nuts & bolts on exhaust system either seize solid, or slowly disintegrate over time from heat cycles. Heat is needed to remove them.

II'm not sure this header/downpipe can be used with the tranny mounted support, but your mechanic should try to free the support of the remaining of your broken bolt.

Guess we'll see if we can get that broken bolt out !
Yeah the new header doesn't have any the same exact shape, so I doubt we'll be able to use the tranny mount anyways...
