Friction disc - 11 3/4" across the disc in the center.
Pressure plate - 11 7/8" across the plate center.
The only numbers I could find on the pressure plate are: LC0080 7K 27B
My engine is a 390 and my transmission is a New Process 435.
So, I have seen that there are 11", 11 1/2", and 12" models. I was wondering which one of these mine fit in...
Thanks much in advance!

Oh and I am sure the 11" one is out because I e-mailed about this one http://cgi.ebay.com/ebaymotors/Clutch-K ... dZViewItem and it was not the right one.
