Does anybody know of online access to an AE Hepolite catalogue which could help me identify some 1960/70's piston sets I have - I'm fairly sure they are Ford Crossflow, just not sure which versions! The reference numbers are: 18679, 18681 (old number17561 - I think these are
1300 x-flow) and 20549 (old number 17566) in case anybody recognises them.
