Thrust I dont know,but from memory, your intermediate bearing is a Hyatt 99000, your input may be a 6211(last two digits I'm not sure)(with circlip groove) and the mainshaft is a 6307. Any how even if I have the numbers wrong the two ball bearings are common as, and will be a stock item at a good bearing shop. The Hyatt 99000 may have to be ordered. With your input shaft bearing, go for the "high load" bearing (slot filled with the extra balls) Buy shielded bearings and in each case remove the shield facing the inside of the g/box.
I dont know if this helps, but the war time 4 speed Dodge gearbox (New Process Gear Company) uses the same cluster, reverse idler, mainshaft gears(1st, 2nd,and 3rd. But not the shaft its self)So if your looking to do the cluster bearings, main pin, or even the cluster, then you may find a scource via NOS Dodge.
Im not sure about the input bearing number, but if your old one is numbered 32**, the "3" is now a "6" (6000 series= metric series) In other words, substitute the 3 for a 6, and the other 3 digits remain the same
