ABA pistons in a 3A? Will they fit?

[mardak at gmail.com (Mark F.)]

I have a set of new JE pistons for sale (83.5mm bore ABA), and someone
who wants to put them in a 3A is interested in them.  My guess is that
unless a different connecting rod is used it won't work, as the piston
pin to piston top measurement is most likely different between the 3A
and ABA blocks.  If this is the case, what size connecting rod will
work (and what stock VW application has such a rod)?

Thanks!

Mark.
