I don\'t know of a kit being offered specifically for G conversions. Hawks has a bare helicoid FS here that will RF couple with most 50mm (really 51.6mm) optical blocks that would fit it. He\'s only listing two diameter measurements so it\'s a bit of a gamble how things would fit. Even the 45G would need the RF coupling tweeked as well as an unknown amount of \"fitting\". I sent a message through that listing for more measurements but haven\'t heard back for three weeks+
Jieying-USA on Ebay has had several M converted 21G\'s FS recently along with pics of all the G lenses converted in similar fashion, pretty nice job. He did respond to my query and is not interested in taking in conversion work at this time. Please keep your eyes out for other interesting G conversions and post them here

Edit: Jieying-USA is now converting Contax G lenses to order. I gave up on my own conversion and sent him my 45G before I screwed it up any further, three days later it was back in the mail to me. Very nice quality new parts, fully rangefinder coupled and calibrated to Leica M bodies. Focus feel is silky smooth (with the addition of a little of my own \"Pedro\'s synlube\"). Focus ring is a little too close to the body but eventually I\'ll add some kind of a tab to it which should solve that. No zone focus scale but RF calibration is spot on.


Here is one: http://www.pbase.com/kkawakami/top_level_contax_g_planar_45mm_mod
(The above does not have RF-coupling, I do not need it.)

Another one: http://www.pbase.com/kkawakami/top_level_contax_g_sonnar_90mm_mod
(For F-mount conversion)
