What sort of money for axles and gearbox ?

May sound a bit cheeky, but how much would you say is a fair price for an auto box for a 97 2.5dse, and axles ?

I have had a lot of enquiries from my breaking ad, but would like an idea of value for them, i have been getting offers around £50 each and i thought that was low, was hoping they would be a bit more than that, am i been unrealistic or is it just people trying it on ?

Thanks, Rob.

tis low diffs got to worth £100 without the rest

Seen a few boxes on Ebay at around the £150 mark. Not sure if they sold though.
