Senior needs help getting an EGR valve off.

Hello! PPLEASE HELP! I'm a disabled senior trying to get the EGR valve off our 1995 Corolla 1.6L Base unit. It failed a smog test and they tested the EGR and said it wasn't working. They said EGR's are expensive, but most of the time they just need to be cleaned out ( which is good because my wife and I are on a very tight income). My son is trying to help me and we got the 2 nuts off that hold the EGR to the back of the intake manifold (of course dropped one and can't find it). However, we can't loosen either the nut that holds the EGR to the pipe coming up from the bottom, nor can we loosen the nit on the little fitting that comes into the side of the EGR. We've tried everything I know (driveway mechanic 30 years) but nothing works.

Anyone know any secrets in getting these 2 nuts loose/off? They are both in a VERY hard to reach spot and we can't get a big enough tool to gain any leverage, and YES, we sprayed the heck out of it with PB blaster - serval days in a row. They are just STUCK. Is there a special tool to get these off? I have a couple pictures, one is from our car, and one is from a new EGR that AutoZone sells so that folks here can see what I'm talking about. The arrows point to the two spots I need to get the nuts loose (that are stuck!). Sorry, I'm old and not to good with technology but I drew the arrows as best I can.

If anyone can help -please let me know! Thanks in advance!!

Maybe WD40 sprayed on and let set fora long time. Just my idea.
