i have a 1979 GMC 1/2 ton, running 15x10 inch enkies all around. tire rubs a little on fenders, has anyone ever shortened a-arms to cure this problem? or can it be done?

That isn't the solution. You will change the geometry of the suspension doing that. You have too little backspacing for the front. I am guessing 3.5 or 3.75" and with a 10" wheel there is no way to keep it from rubbing.

That's the way it used to be done back in the day, guy by the name of McCoy down in SoCal, had a shop called the Drop Shop and they would section the lower A-arm's by removing a strip of metal near the ball joint and reweld it back, this worked in conjucntion with cutting the coils to get your drop and keep the alignment specs within, this was before they came out with drop coils and lowering Aarms for our trucks.

No, the Drop Shop didn't shorten them, they raised the balljoint up, basically lowering the spring pocket, I did the same thing to mine... In 1988.....
