PBY-6A or PBN conversion parts

I am trying to complete a run of the PBY series. I have the -2, -4, -5 &-5A (all from Academy) and was wondering if anyone knows if -6A or PBN kits or conversions are available.
I saw a passing reference to the Broplan vac conversions for both, but cannot seem to find any information on the manufacturer. I do not even know if they still exist. I cannot find a company site via Google, anybody know if they are still in business?
I have also seen the Revell kit of Cousteau’s Catalina. The seem to get rather expensive on eBay.
Anybody got any other Ideas?

What scale?

At 1/48 scale Belcher Bits has the -6A / PBN conversion for the Pro Modeler PBY-5A kit. Should be ok with a little bit of work for the regular Monogram PBY-5A kit.

Sorry, my bad. I am working in 1/72 not 1/48. Thanks for the info though.

PS how is the F4F-3S Wildcatfish coming along? I have the conversion and am just waiting for the base kit to arrive.
