Technical Y block 10" pressure plate

Hey guys i have the original 239 in my 54 ford. Putting a t5 behind it. Car has a 10" clutch in it, i found a 10" disc for the t5 input shaft easy enough but im catching hell finding a 10" pressure plate for this car. Macs and all only list a 9.5" clutch for 54 and the right up to an 11" for 55 and up. They list a 10" disc but no pressure plate. Anyone have a part number or know where to get em at?

 

try Pauls clutch in Boston....or Ft.Wayne clutch in Indiana.
