Citroen relay gearbox

[Tony H]

Evenin' all, can anyone give me the "heads up" on how difficult it would be to change the gearbox on a Relay 1400 1998, 2.5 diesel manual 5 speed non turbo gearbox using ramps if that's possible. As my works vans box has just packed in.
Thanks in anticipation for any advice

We have a similar aged van that needs a new clutch, I think we've decided the best way would be to remove the front bumper, radiator, panel, etc. rather than go in from underneath...
