Can pistons from a JX be used in an RA??

[Mark(The Miser)UK]

My ETKA shows 068 107 065 BC for the CY as one would expect

CY as in the engine I have in my mk1 GTD

What a mess...Just checking... OK so you have a GTD that dated as to 82/83 ish? Non intercooled? Golfs did use the CY TD  then, and you are correct, used the BC piston Then by late 1984  Golfs had the JR. 

The CY was unusual in that it survived becoming hydraulic. 1981 to 1986 in the 'mk2 Passat [Quantum] was also 'BC' . It was on turning hyfdraulic, that the piston in CY  became same as RA/SB.

I'll amend  the list thanks. What edition of KATE do you have? I have version 7 and 5.5.  I'd love an earlier  version

It's so full of blanks of the interesting stuff at crossover between mk1 and mk2.

Does anyone have an early Euro 'KATE' [ver 1 , 2  or 3?] out there who could send me a copy?
