hi. im curious. i dont have a plumb centre near by. id like to get a few combustion caps for turbomaxs, glowworm cxi, worcester cdi as ive noticed its increasingly common for these to be missing. !!!!an inspector of my firm went in to a flat , hadnt noticed combustion cap missing and then i go in to service it and cap it off!!joker. qc with 40 years experience .rather then creating drama it would be handy to have these on my tool kit. know how where i can order? part number eyc. thanks
