What timing cover are you using with a 7.3 inch damper

This is your initial post and you "DO NOT" say WTF you have.

"G’day. I’ve bought this type of harmonic balancer, with the timing case pictured, balancer is 7’3 inch diameter, looks like it will hit the timing marks on the timing case before the balancer will go all the way on."

People like you who are argumentative and defensive piss a lot of the "OLD" time members off. Some of us have been in the MOPAR game 20 years longer than you have and really like the advice and suggestions here because we "DO NOT" know everything. If you get your shorts in a twist because you were wrong, maybe you need to find another source of information.
