Just so you know, you can drive the new seals in using an FE harmonic balancer spacer and a compothane hammer. It's the right length and diameter. I used one of the old seals backwards against the new seal as a buffer between the balancer spacer and the new seal.
Also, pack the backside (where the spring is) and of each of the seals with TransJel; it helps keep the springs from poping out during the hammering-in process. Also put a little TransJel on the inside and outside diameter of the seal to help slide the seal in without damaging it.
Resealed without removing the box.
Worked perfect.
