What timing cover are you using with a 7.3 inch damper

Not sure how I'm being passive aggressive, but what ever!

For someone who has "been in Chrysler for 30 years" you don't seem to know much.

Have you considered contacting the damper manufacturer and ask for what they recommend?

They built it and so there must be a cover available that will work.

Lastly many of us have no problem using used parts.

Have a great day.
Ya haven’t quite worked out, I’m in Australia. Not a great deal of used parts, any that are about they want top dollar for.
And don’t start **** slinging….
