Hey, folks. I've got a early '74 260 with a 5-speed swapped in. It's becoming progressivly harder to shift into first and somewhat hard in other gears, especially when not moving. I'm getting grinding / clashing when shifting. I've taken to double cltuching and heel-toing in order to get the shifter through the gates while driving. The problem is at its worst when the car is cold, and when warm, it's atually not too bad of a problem, although it's still difficult to shift at times. I'm told that the throwout bearing might have been put in backward, or is going out, making the clutch not disengage completely. If it was put in backward, it may be getting machined down and made thinner, causing the clutch not to completely disengage. I'm not completely sure this is the problem. I've got a throwout bearing to put in, but I'm wondering if I've got the right part. Could anyone give me part numbers for a 4-speed bearing and a 5-speed bearing? Thanks!
