Hi TAU44, the answer to the first part is easy enough, YES!

You need the axle and cast pivot and tie rods, and it will bolt on in place of the narrow front. Just remove the bolts from the pedistal, and bolt up the wide front.
The second part is a little tougher, the price depends on the area, around here, agood wide front complete will go for $100+. Check at some tractor dealers/ salvage yards in your area to get a ball park for your area.:thumbsup:
