Two Questions.
 

Raided a well maintained 73 450sel at my local U pull it type place. Found a really tight distributor but the connection to the trigger points is different. It has a round connection and mine has a flat connection. Will the trigger points from a 72 4.5 fit in to a 73 4.5 distributor.

What is the size of the allen wrench holding on the cam towers? I didn't have my set with me and want to have the right size before going back.

The trigger points are interchangable. Keep the old set as they also will work by changing the connectors.

I think it was an 8mm allen on the V8 cams.

Thanks stevebfl
 

Thank you very much for the info. Tomorrow I'll get the cams if there still there.
