S14a downpipe Trouble

[Notty]

Hello people trying to replace my turbo and I’ve got everything lose except the down pipe from the elbow, now as far as I’m aware there are two bolts I’ve taken off from the top of the engine and one that needs to come off from underneath the car, is this correct?

Or have I done it all wrong?

The one last bolt I’m trying to take off from underneath has rounded and it’s pretty old and rusty, don’t know what to do!

It's a while ago since I've had an s14a but I know there are 3 bolts. Lots of WD 40 and vice grips of possible to get in at it. Maybe put a bolt in on top again to take some of the pressure or strain off the last bolt. Get new bolts/nuts too
