I do not recognise the part numbers that you quote, and I don't believe that Bedford fitted 'Leyland' gearboxes to VALs even though early models were fitted with the Leyland engine.
I can only repeat my earlier information:-
http://www.truckandbusforum.com/arch...hp/t-3822.html
and recommend that you invest $15 in a copy of the workshop manual for the Eaton six-speed gearbox:- Bedford.E.N.V.Transmission type 542 SMOT.Service training manual.TS844.
from:-
http://www.mark.clubaustin.co.uk/commercials.htm
or:-
010843 Bedford E.N.V. Transmission Type 542 SMOT Service Training Manual (photocopy), 12 pages, $15.00
from:-

$15 doesn't seem like too much to pay if it confirms that your gearbox is indeed a six speed ENV.
Hope this helps.
