Custom 250sx tips and help

[davrei87sx]

I have purchased a 1987 250sx in great running condition minus brakes (front and rear pads worn out) for $900. The seat is mint and the plastics are great except for 2 small cracks beside the toolbox lid. I just ordered 14" ITP Type 7 rims with (2+5) offset. 26x11x14 zillas and 1.5" wheel spacers for the rear. Tomorrow I am picking up a 200x minus engine/tank/plastics for $75.

I have a few questions as follows:

I would like to convert my front end to the 200x.
Should I use my existing triples and just run the 200x fork tubes and make spacers for either side of the 200x tire?
If I use the entire 200x front end will my 250sx front fender and headlight fit?
What is the 200x front rim dimensions and offset?
What is a good steering tire for trail and mud? What size front tire should I go with?

One last thing that I am tinkering with in my mind is a rear end disc brake conversion. Could I fabricate a spacer to bolt onto the inside of my right tire hub with a disc mounted to it? Then on the rear axle housing weld a bracket to bolt the 200x caliper to? Anyone try this or is this wishful thinking?

Any advise or input would be greatly appreciated!

Here are a couple pictures of the 200x I'm getting. I have 1 picture of my 250sx from when I bought it

Most people use the entire 200x front end, personally I just used the 200x forks, hub, wheel and brake caliper. I used a 24" tall AT489 tire for the front and like it so far. New spacers have to be made to center the hub on the axle and a spacer for the brake caliper also has to be made for that to work. Not sure about using the entire 200x front end, but if I understand it right it is a bolt on and go deal.

After reading a little, you may or may not have to replace the steering stem bearings and you do have to add a steering stop.
