Need input on 87-93 wheel sizes

[Twirkin50]

I am looking to put 17X10's on the rear of my 91 LX. Will they fit?
If so, what backspacing is needed?

Also, if I want to convert to 5 lug rear disc can I purchase strange 31 spline to start the conversion?

Thanks for any info!

You will need 6 to 6 1/2 inches of backspacing. They will fit. You will have to massage the inner wheelwell a bit though.

Thanks for the info, I already have the fender lip removed and the inner massaged from my sportsman pro's. So, I just want something different for street driving so I figured lower it a little and throw on some 17's, then switch it up for the track.

Anyone have any info on the five lug? I want to go disc in the rear, but already have a lot stuck into the differential and c clips, so I was hoping to just get strange 31 spline 5 lugs.
