Front Servo Question

Thanks guys! Well, I opened up the bigblock 727 core I have and low and behold, it had a 3.8 kickdown lever. I pilfered it and will attempt to replace the 2.9 lever in the 68 that I'm working on with it. Hopefully I can get it in without dropping the trans. Wish me luck... Has anyone else been able to replace the front band lever in the car with converter in place??? Any tips??
