stugilmour 7 Report post Posted June 23, 2013 I had checked with Holloway a few months ago, and he has sold his last kit earlier this year. No plans to make more. I ended up going with the GTO Racing kit instead. Good luck in your search. Quote Share this post Link to post Share on other sites
Tallic 0 1 Vehicles Report post Posted June 25, 2013 Holloway told me the same thing. How much was the Gearbox from GTO Racing? Quote Share this post Link to post Share on other sites
stugilmour 7 Report post Posted June 25, 2013 (edited) The kit was 2,634 GBP including ~100 GBP shipping to Canada and 290 GBP for a spare (good used) synchronizer and sliding hub. I bought these as we did not know what my gearbox internals were like prior to tear-down and the shifting quality was poor. I ended up able to get a new synchro from a NA supplier anyway, so the one from GTO is spare. I also had a Quaife LSD installed at the same time, but the tech in Vancouver had one in stock so purchased separately. GTO can supply the LSD though. Delivery took a while. Best of luck finding a Holloway. I heard a few leads on a kit but was unable to get one. HTH Edited June 25, 2013 by stugilmour Quote Share this post Link to post Share on other sites
