Thunderbolt is new to me, even after googling "Glow plug adapter/gas-glow conversion/etc" any combination thereof, it did not come up as a hit.

but Ihave already contacted fujiman, and he has been very helpful. Excellent ratings, and he comes across as a honest seller, He posts lots of comments and genuinely likes to help. I will be giving him my business.
