Replace Tray on 99 Hilux with ute body

Hi All,

I have been looking for a while for a Hilux Ex-cab and have been offered a good one for a very reasonable price. The issue is however that it has a dropside tray which I am not keen on, but an considering removing this and then getting a style side ute back for it instead. Has anyone done this before? I think it should be pretty straight foward, but not sure about the fuel filler and if there is any other differences I am not aware of e.g. fuel tank placement, mounts etc.

I'm thinking I can get the new back for it from a wrecker so should be able to get all the parts I need, but if it is too much trouble will not bother and keep looking.

Thanks for the help.
