Hi Tom,
It is much easier to do this (although this job is not easy), if you remove the
carb and most of the stuff above the area of the cat.
Then get under the car and remove the bolts that connect the cat to the
downpipe.
After that remove the bolts that attach the cat to the manifold.
If the bolts are seized, use PB Blaster t oloosen them - it is miracle solvent!
If that doesn't do the trick, remove the whole manifold and have the bolts
flamed at your local mechanic or machine shop/welder.
They heat the bolts up until they are cherry red, the nthey come right off.
Once you get them off, replace them with new bolts and brass nuts - you won't
have the problem again.
If you take the manifold off, buy a new manifold gasket - no skimping here!
Erik.
