Distributor Cam Plate

Hi I am looking for a Single Point cam Plate stamped R10 (right hand rotation) to suit 1967 273 single point distributor. I have attached a pic of my dizzy stripped down it has a r16.5 with the slots at an angle.... I am looking for a cam plate that is either NOS or in excellent condition with the slots running parallel not on an angle like the one in mine. My distributor is #2642805. cheersIMG_3078.jpg
