can some one tell me if 17x6.5 rims will fit a datso 1000 ute,

no chance

Not if you want to drive it.

Cut the guards out, bolt on flares, it might be possible.

what will fit on there

Try to keep the outside diameter of the front tyres down to about 550 to 565mm. This is close to the original diameter & it will clear the footwell area.
A 5" wide rim works great, while 6" rims start to give a little grief with the top of the front guard wheel arch.
The diameter of the rim is not so important, but the diameter of the tyre IS, & 185 x 60 x 13's are a good choice under the front. If you stick pretty close to this tyres diameter & tread width, you should have no real problems.

Rears can be wider & larger, but you will need to trial fit to be sure.

dose any one no of a good looking rim to go onto a 1000 ute

Minilites,Panasports and Watanabes are all similiar looking old skool wheels that look good on old Datsuns.

I've got 17x7's on a 1200 but I dont know if the wheel arch size is the same and if they are I had to modify the front wheel arch so that the wheel dosent hit when you turn if you go to my picks you can see what I mean

just remembered the skinniest tyre that I can find is a 205 and I personally think it is a bit too wide on the front as compared to a 195 but no one in mackay can seam to get them for me
