Need help finding right vacuum advance pod

[rednesss]

So from what I can remember, I have an old MP distributor from the electronic ignition conversion kit, from the late 90's. So I was checking the vacuum advance and it does not hold vacuum, it bleeds off, so I decided I should replace it. But I'm not sure what part number to look for. The current one has an 8.5R stamped on the arm. Can anyone give me some NAPA part #'s maybe? Thanks.

I'm wondering if this wouldn't be the one.

Looks like the right one to me.
You can decrease the amount of advance by bending up the case with a slot screwdriver where the red arrow is.

I have the correct one sitting right here in the box.
It is a Standard brand part # VC190 and has VC228 in smaller font under that.

The one pictured should be the right one.
