I just ordred main air & fuel jets, & a progression hole plug for my DCD and they were in stock. They only had 3 size 250 main air correctors left though and I bought 2 of them. They also have rebuild kits and needle & seats. They do not have any Grose Jets though, they said they've been on order for a long time and from research I've done D&G Valve Co is either out of business or not making the Grose Jets anymore for anything.

This is for the dual 36 weber DCD kit by Rotary Engineering. Which came with Grose Jets (mine are well used and stuck).

Sorry, a bit off topic, but do the Grose Jets flow more? When I rebuilt my pair, I noticed those in place of the needle valves and just re-used them since they looked like they worked better.

 

Yes. They flow more, spray in a 360* pattern, seal better, and handle G-loads better. Best thing since before sliced bread. Unfortunately NLA.
