Hydramatic Seal Replacement

I need to replace the transmission seal on my dual-range Hydramatic (1953 Hornet). I have a seal that I can use but it will not accommodate the seal dust cover. The original seal has an overall thickness of approximately 7/8". The replacement seal I bought is only about 7/16" thick and goes completely inside the tail shaft housing. The dust cover fits over the original seal. Does anyone have a part number for the original type seal and where it may be purchased from? 
Thanks!
Joe

    Hi Joe
    U can easily remove the dust cover with bi-scrips and a hammer. To replace your seal. So tranny did not have them is really isn't needed

    I have ordered a couple sizes from Dave Edwards of Autotran. He had a 1" that is for a 51 Olds and also a 3/4".
    I'll see if they will be usable. He said both of the seals were made by Chicago Rawhide. Thanks to Russ and Ron for the information.
