seat pads

thank you for the assistance last week on interior colors. i have ordered leather interior from gahh (seats, door panels, seatbacks, convertible deck, etc). plan to have it this week, and work on it this weekend. although i can't really say there is a problem with the seats pads - the leather itself is dried, cracked, and taring, so i'm guessing that maybe i should just plan on replacing the pads. i really don't want to get seats ripped apart, and then have to order and wait for new pads. comments on this aspect?

and if i decide to get new pads, any suggestions as to going with horsehair, rubberized, and/or which vendor? are seatbacks generally okay, and just the bottoms?
