Advise on Tremec 5-speed
 

I'm close to pulling the trigger for a Tremec TKO600 5-speed for my 66 BB roadster and would like to hear anyone's opinions and comparison between the 5-speed kits supplied by Silver Sport Transmissions (TN) and Hurst Driveline Conversions (CA). From what I can tell they both provide a near identical package at close to the same package price with really the only difference being their off-set shifter setup so the shifter fits a C2 tunnel hole properly.

Does anyone have any comparative experience between the Silver Sport "Perfect Fit" mechanism and the Hurst "Sidewinder II" mechanism? Has anyone with either of these setups had any problems with shifting? Is one design better (ie: smoother) than the other in your opinion?

I'm really looking for comments from users here who have experience with either of these 5-speed conversions in a C2. It's close to a $4k purchase so if one design is preferred over the other, I'd like to hear about that. Thanks in advance. Bill
