If you remove the valve completely there is no elegant or effective means of blocking off the cat.

Yes, that is a problem. AFAIK, there is no easy way of blocking the exhaust outlet from the cat. The copper disc that I provide with the kit won't work at that location. You'd probably have to weld it shut with a steel plate.

Begging your pardon, Brian, your copper disk fit perfectly in the EGR outlet of the trap cat on my '85 300D-T (California version).

Thanks Jeremy.

I've therefore got conflicting info regarding the CA vehicles. Some have the same interface as the Federal vehicles as shown in your photos, and some do not.

Oh well...........it's touch and go with those vehicles with regard to function.

I wonder if the "trap oxidizer" (which had to be changed every 30,000 miles) was externally different from the "trap catalyst?" My car has the "catalyst;" I've never seen the older "oxidizer."

What are the identifying numbers on your catalyst? I am trying to determine if my 'football' has been swapped yet. The car is new to me and I can't tell which one it is (1985).

I'm getting ready to pull mine and will be able to read the numbers, if any, at that time. I will post them here.

Go to a dealership and ask them to look up the recall records.
