Hybrids are quite expensive for the gains made, I'd go with a rebuilt CT9b. Either that, or get an adaptor plate from Dean at RW-D and run a TD04/similar
Now that it's been revealed, I can say that I've been thinking about this swap for a while for my GT haha Hope all goes well mate, will need to get details off you for the people who are doing the conversion!
Nice John! It's slightly different to the '98 spec lenses though, the black triangle-ish bit is chrome (I sprayed mine too), but looks good nonetheless!
