yes the plates are available new, they are #172 for both primary and secondary.One oddity of CJ carbs in general is by their very nature of how the throttle shaft/plates set up, you will expose more transfer slot than normal. This is part of why the idle feed can be set so lean. Part of this is the plane in which the throttle shafts are machined, and the thin plates.A trick to look out for, the secondary plates are 172 and very very thin, this makes setup critical so you don't have an exposed secondary transfer slot.I like to use the short vs diaphragm with these or often the secondaries will not fully open.
The stock spacer is 4-hole, would that make any difference with the Streetmaster open plenum?
