    Good luck bill, not a job to be taken lightly.

    Hope you have a dial gauge and micrometer for the end play shims and spacers or it WILL whine

    You could use quality feeler gauges but a dial gauge is much more accurate.

    As I said, if the end play is wrong or sloppy it will whine.

    There's always sawdust though :LOL:

    I never could work out how gear boxes worked Bill, even the old one on my Rudge.
    Take care

    Broken selector fork or maybe the pin holding it to the selector shaft has sheared off or, more unlikely, worked it way out.
    With any luck you might not have to remove the actual input, output and idler shafts providing the selector shaft is under the removable cover and not behind the gear shafts.

    i was thinking, if you have a donor box it may be just a case of swapping over the bell housing. as i recall the gearbox on all vans that age was the same, just bell housing differs

    What @pappajohn suggested, the selector fork or shaft pin.
