The front of the cat has a flexable connections with bolts and springs. No
problem here. The back end of the cat has three threaded studs/bolts coming
out of the flange. I'm hoping to reuse the cat but I cannot get these three
bolts out of the cat.. I had to cut the rusted nuts off to disassemble and I
need to be able to bolt this end of the cat onto the new pipe I'm replacing.
Looks like I'm going to have to grind the flange flush on both sides and
drill the holes out to accept three new bolts????

I've never seen perminant bolts like this?? I've seen a fixed nut on one
flange but not the bolt.????

When I look up new Catalytic converters it looks like there are holes there
not threaded studs???

Could these bolts be badlt rusted in place? I wacked it pretty hard and have
just about cut one of the "heads" off (they look like a "t" head not a nut
shape) and the shaft of the bolt wont budge... Like its part of the flange..


Is this unusual????


Thanks
