I picked up a 904 awhile back, the guy said was out of a 78 or 79 aspen. I posted the # on the pan rail which is 1 PK2892027 2292 0000. A member here says its a 68 according to his book. So when I look up a kit on Ebay they offer kits that fit 62 -65 and another from 66 -92. Looks like the early kit has 6 clutch discs and the later ones have 8 Dodge A904 904 Torqueflite 6 Transmission DLX Rebuild Kit TF-6 TF6 1962-1965 | eBay
