Then before applying heat, I tried a hammer and punch to persuade the remaining bolts. Started on the driver's side. The bottom bolt came flying out after 3-4 shots and one of the upper bolts came half way out from the force of the lower bolt. The 3rd (long) bolt took a bit more persuasion, but eventually it came out too. Moved to the passenger side. The lower bolt was the 1st one I tried in this whole endevour and it was stuck. Moved to the top 2 and they both came out. Took a small screwdriver and tapped on it between the flanges, being careful not to cause any gouges. It popped. I hammered the bolt and it came out. 6 bolts out.


Had to buy a 27mm open end wrench to get the pipe to the cats off. Took me to 3rd try but found one at an Advanced Auto. Used a 22mm flared wrench on the bottom nut. The 27 wouldn't budge. Ended up putting some heat on the nut and it broke loose. The exhaust pipes are down, the bell housing plate is off, and the CPS is in.




I got the fuel lines back in this afternoon. Back on track for a starting attempt.
Appreciate everyone's input.
With a car with this much corrosion, order a can of Kano Aerokroil. Start spraying the hardware you want to take apart, a couple of days before you start working. If you put wrenches on the hardware and it still doesn't budge, stop immediately and heat the nut until it glows red (induction or oxy/acel torch. Map gas is like hot glue...products for chicks.) As soon as the nut stops glowing, remove it.
