Stage III, you may want to change your request to a "block saver plate"; it may garner more attention.
I would check with a local fab shop. It would be really easy to make one. it might get tiresome drilling 45 holes though!
If you have a template,I'm sure Steve Reynolds can make you one..He made my midplate for my car..Wont take much more to make a block saver plate..
Call Quick Time and see if they will sell you a block saver. They’re still making their scatter shields and should be able to sell you just the plate. Lakewood discontinued their scatter shields and stopped selling just the block saver plates about 12 years ago.
I'm packing up my warehouse to move my parts to our new home/shop and I found a block plate for a BOP. If still in need, email me direct: drolds1@bellsouth.net. Thanks, Bob.
