$350.00 sounds about right.
Paint materials are very expensive.
I have swapped 1,000's of fenders in my life. I can't recall off hand if I have ever done a sport-trac though.
If you are going to try the swap yourself here are some tips.
Run a few strips of masking tape down the front edge of the door to protect the paint on the door. There are tabs on the fender that go behind the door that could really scratch the door when the new fender goes on.
A five minute short cut is not worth ten minuets of frustration. Go ahead and take the bumper cover all the way off. Take the rocker cover all the way off. Take the headlight all the way off.
When you go back on with the new. Put all the bolts in loosely. Find a tiny flat head screwdriver. Go to the good side of the truck and put the tip of the screwdriver between the door and the fender. Note how far it goes in, use that as your gauge to make the gap on both sides match.
Start with the fender bolt behind the door at the top. Get the gap at the top between the top of the door and the fender right first. Next do the gap at the bottom of the door and fender. The top might have moved, go recheck it. Recheck the bottom gap.
Got them even top to bottom and matching the right side? Is the in and out even with the fender to the door? Good job !!
Verify you can open the door with out it contacting the fender.
When doing the hood to fender gap I prefer to remove the latch so I don't have to walk back and forth to keep popping the hood.
Start at the very back and match the gap there first. Tighten the very back bolt only.
Now match the very front. Tighten the front bolt. The gap in the middle
should be just right if it is, tighten the middle bolt. If it is not then loosen the front bolt. Set the middle gap, tighten the middle bolt, then do the front again.
Tighten all your bolts.
Have a lemonade.
Now to reset the hood latch.
Verify your gaps and height adjustment. Adjust if needed.
Bolt the latch in the all the way up and centered position.
Close and latch the hood.
Using a long extension, crack all the latch bolts loose a few turns. Make sure the latch is latched and you can jiggle it a little bit.
Put your hand on the hood right above the latch and push down just a little bit.
Tighten the latch bolts.
Go test pop it. Hold the hood about six or eight inches up, and drop it. It should latch with no issue.
Put everything else back on as you took it off.
Do note: Unless your Trac is black, the odds are going to be slim you are going to have an
exact color match. That is a consequence of painting the fender off the vehicle and not blending the door panel.
Good luck and please don't forget to post and let me know how it went.
Don't hesitate to ask me any more questions either. I am glad to help.
