Wanted to stop in and say high and ask a few Q's! Been aroung Mustangs since I was 16, had a 75 II as my first car, been into the foxbodies ever since, finally picked up a 68 coupe, orginal 289, c4. Just recently restored. I'm adding to it and have a few questions. I've searched throught the forums and seen case fill and pan fill. From what I can get the 70 & up were case fill and 69 below were pan fill? Also 24 spline on older years and 26 spline 70 and up. My question lies in that my 68 has a case fill from what I can tell the tube goes in the case in front of the servo. So is my tranny a 26 or a 24 spline and is it the original tranny. Havnt ran any #'s except the door code. I plan on pulling the motor soon, got a great deeal on a H/C/I combo from a buddy. Just wanted to get things straight on the tranny. I just bought a TCI valvebody but it says its for 70 & up?
