2.0 Piston! But what type?
 
Have this set of 2.0 pistons and not sure what model/year they are off?
Mahle USA say they are 68,69T they should know right?
Wayne in your book photo 4-21 showing the cut outs for valves on S and T piston tops has thrown me. My piston top looks more like the S? But mine don't have the small skirt of the S.
Also the ring below the pin should date it, no?
The box has 64 on it, surely not the year?
Inside the piston is SOV65+ and CO11 and 34 7 in a ring
Does that 34 relate to the week and the 7 the year? 67?
Top has 79.97mm and Sp 0 04 and 110M107
Help!!!http://forums.pelicanparts.com/uploa...1076233427.jpg

2.0 Piston Trauma?
 
Ring sizes of 1.5,2.0,4.0 make it either
65-69 911,911E or L
68-69 T
but are the piston dome and valve cut outs T?

They look like 1965 2.0 pistons to me...

That would explain the 64 and 65 numbers, but what about the large valve cut outs?

Again: They look like 1965 2.0 pistons to me...

There was only one piston available for the 911 in the early years - they looked like these...
