1-7/8 primaries for 2" ones

[sam919]

Im looking to get some more out of my duratec so swapping the 1-7/8" primaries for 2", is there anyone/ team/ enthusiast looking for such items? They are good for 300hp and have been running a 4-1 collector.

Thanks

They were developed by HWR engineering and AAS in Newcastle, about 18 months ago.
