i have a 1987 GMC jimmy (fullsize) that has a 4in lift and 35's. My plan is to get 6in lift springs and put on 4in blocks on the back (making a total lift of 10in), and in the front put 8in lift springs with a 2in shakles (making a total lift of 10in). I plan on getting a set of 38/16/15 boggers.

my questions are:
1) what width rim should i get for a tire this size?
2) will the stock 1/2 ton axles hold up?
3) what gears should I run?
4) I far will i be past legal limit for height?
5) will the angle be to big for the stock drive shafts?

also any sites on where to get stuff.

thanks
