What Honda cam gears are these?
 

New to this forum,great stuff,but anyway onto my problem.
I have a dodge 2.5 turbo with a neon dohc16v head adapted to it,and use some cam gears from a Honda sohc12v engine,'90 or so model I believe,but can't ID them exactly.I thought they were from a A20a series,but this style has the wrong off-set compared to mine.The ones I am using are cast steel 40 teeth,and have a maximum off-set meaning the 'spokes' of the gear are at the very outer edge of the toothed ring.They have PK1 cast into a couple I have,but others don't.
I REALLY need to find the exact model these came from.I searched the yards for more and can't find any at the moment,and the dealer I tried couldn't help me much.I hope this is in the right section...
