An update here.
We reached out to people who purchased affected kits and posted here last night in an abundance of caution, but we did hear back from Dan and Eileen last night that this issue was caught in January and the kit in question hadn’t been opened yet. This means the likelihood of you having the issue we raised is pretty low.
I do encourage you to pay attention to part values prior to installation. We do our best, just as Dan and Eileen did, to ensure you get the right parts but mistakes do happen from time to time.
As always, reach out to us here or at info (at) bottlehead.com if you need anything.
