its bout 1500 aussie for conversion to fit manual to 1uz
this includes all parts but not gbox
std hilux box is strong but u will break it if u abuse it
u can go for bigger box but its more expensive
but decide what box u want cause the custom made bellhousing for the manual sometimes will only suit one box and if u upgrade box u might not be able to get bel;lhousing redrilled
i think some can and some cannot be redrilled
anyway its not cheap
