Default 94 Cats and Exhaust

I am putting my 94 LT1 back together and it seems like the cats that I got are the wrong ones, they seem to fit okay but no bung for the O2 sensor and no stabilizer bracket on the passenger side. It may be a little tight against the starter as well...
It also seems like that the one piece exhaust I got for it is wrong too. It does not reach all the way to the flange on the cat on the left hand side, any ideas on what is causing the differences I am finding?
Is there an alternative I could use, any recommendations?

Chris

Do you have any pics of the cat and exhaust?

I forget what year they started with 3 O2 sensors, and the passenger side pipe slides on and overlaps a few inches.

I don't have a way to get a pic right now, but once I get it up on stands...
It does have the slip over connection on the pass side but the beveled flange on the drivers side is about 8 or 9 inches away from being able to connect.

Just a guess, but maybe it's a ZR1 exhaust system with LT1 exhaust manifolds?

:confused:

I thought that may be the case as well but the picture in the helms makes them look considerably different on the ZR1, and these at least look right but aren't...

Helms is full of typos and bad pix. Besides, it's the only thing that makes sense.
