LT1 Cat Bracket Removal - How to? HELP!
Well I am at it once again and have run into another snag. I have pulled off the catback, the passenger side header and am left with the driver's side cat and bracket and the passenger's side cat bracket. I was able to remove these while the C-Beam and the Driveshaft were out because I was able to tilt the engine and transmission down, but as it sits, I see no way of getting the top bolts out from the brackets. I was hoping to have these long tubes on tomorrow but it does not look promising.
Am I missing something? I can get a socket on there but with out a rachet. With the swivel on, there is no room to move. And forget about putting a wrench on there.
Someone please give me some ideas becuase I really do not want to have to unbolt the C-Beam and Driveshaft.
Thanks in advance,
Dave

I found ye olde 'Blue Flame Wrench' to be very helpful when removing mine long ago!

Those bolts are a biatch, just so you know, with patience you CAN get the drivers side out from the top. Remove the valve cover on that side, remove the windshield wiper motor assembly and there is just enough room for a wrench to fit down there. Still a pain but if you plan on re-using your cats you should have that bracket there.
The passenger side isn't that bad, a really long extension and swivel and it'll come out. Helps to have someone up top to locate things for you.
Only other way is like mentioned, tilt the engine tranny assembly down a bit and have at her.

The cats connect at the manifold and the exhaust only.
Is this something that started in '93?
