I recently completed MDL's Tremec TKO 600 5 speed conversion on my 66 Tiger! http://moderndriveline.com/Tiger_TKO.htm I am very pleased with the results and the conversion went without a hitch. I expect it will be much more comfortable on long interstate trips now with the .64 O.D.----3k rpm's at 65 mph now drop to 2k in 5th. I still have the 2.88 rear end and so it was also a nice surprise to feel the slight reduction in first gear (2.87 vs the 2.32 in the old close ratio Toploader). The 600 bolted right up to my 6 bolt bell housing. I swapped my old 10 spline clutch disc for a 26 spline to fit the 600. My kit included a new drive shaft and cross member.
Others with 5 speeds have said "it'l be the best thing you'll ever do to your Tiger if you take long trips". I believe it now and it feels good to be there!
