Mike, as tmodelman posted, you use some modern clutch plates. These give you a much better neutral for start in cold weather. It is also a good idea to replace the clutch spring as they do get weak. Proper adjustment is important with these clutch discs replacement. If you let them slip while driving for just a little while, they will wipe out the lining on the disk and that means replacement again. So listen to the engine and if it speeds up and the car does not, the clutch is slipping.
I have them in more than one car and if I take a transmission out for any reason, the new clutch discs go in.l
