Thanks for all the info. It will be a little bit before I can try some of these things. I will call McLeod for some specs and check the price to swap to 18 spline. I will look into the fluid issue. As for new shifter and clutch linkage, it's all new. Correct hurst shifter. All clutch pivots and linkage were missing when I got the car last year. Finished complete restoration in June 2012. Everything is new. I don't thing the mounts are metal like the last poster mentioned. Do I get that from hurst? Also the more I think about this it seems the best idea will be to get a hemi 4 speed and change the Dana 60 from 4.10 to 3.54. According to the calculator on summit direct drive 4th gear 70 mph on freeway with 3.54 and the 30" tall tire I have it will run about 2950 rpm which would be ok I guess. My 68 Bee has a 727 where 3rd is direct drive and 3.23 gears and same M/T tires. I turn 3000 at 75 mph. In the orange 69 I'm about 2500 or so now.
