Bought, actualy more like stole, a large input toploader with factory Hurst shifter out of 1970 429 Ford Torino today for $200. Looks good inside. A little normal wear on the dogs on the gears. Plan  to have it taken apart and checked out and put in new syncronizers and small parts kit. Will have to change the driveshaft yolk probably. Will definately have to change the clutch disk to fit the large input shaft. Will have to have the hole in the belhousing machined larger so the front snout will fit. Will need larger throwout bearing and retainer. Does anyone know if the clutch fork will work ok with the larger throwout bearing? Am I missing anything in this conversion? I will be installing it in my '57 Tbird. I now have an all syncro 3 speed out of a  '64 390 Galaxie in the car. A 4 speed from a 390 would have bolted right in but I could not pass up the large input trans for the price.
