TRW was bought by ZF some years ago.

Wow, thanks for the link. That was quick. So they are +40" which is what I measured. Just need to know the make and cc of the dish.

TRW is the make: https://en.wikipedia.org/wiki/TRW_Automotive update: wrong link!

In the other thread the dish was mentioned as the same as the standard pistons. Obviously they were oversize replacements for the standard pistons.

Hi, I believe the pistons are not necessarily made by TRW, but could be just branded. Inside the skirt will probably be a casting or forging number on one side, and a manufacturer logo on the other side. That may tell you who made them. Cheers Lindsay
