Hey so here is 2 quick questions. A buddy of mine is willing to sell me the front Dana 40 out of his 1973 Bronco. Now will this fit under my truck with no fabing of the actual axle it self. I.E having to pull the tubes and then shortening them etc etc. and 2 another buddy of mine is selling his super swamper's that are 35s. the are off of a 2000 Chevy 1/2 ton. Will the bolt pattern be the same .
