Does this distributor look like a Summit/Firecore distributor? The only number on it is "A-1" on the bottom of the housing.
It came on a complete low deck engine a friend bought, but didn't have a cap on it. Just need to know what it is so we can get a cap and use it...maybe.
It does have the MSD style plug, but it's not an MSD piece.
I think this is SUM-850082-1
