Could someone please tell me what models these precombustion chambers fit? I can’t find part numbers on them and I have a few of each I’d like to sell. Thank you guys for all your help,
Robyn

Best guess is the O.981 (1" nominal) is for early D2
The 1.112 (1-1/8" nominal) is for early D4, D6.
The 1.215 (1-1/4" nominal) I'm not sure of application but if a 1-1/2' hex head fits it's for the early 5-3/4 or 5-1/4 bore engines.

Hi Robyn,
I do have the scans below but that is all at present.
Orifice sizes are critical to application and the scan of the D311, D315 and D318 diameters given are likely to be for the body size--I am unsure what they are actually referring to be honest but thought they may assist you in your quest.
Good Luck.
Cheers,
Eddie B.
