My Cherokee 140's wheel pants developed cracks in them and had tobe removed. This was discovered at annual while going for the knots 2 u speed pants. I purchased some replacements off the internet. They are gray primed and they are not cut out for the brakes or drilled. I will have to have someone cut the insides of them out to fit around the brakes and drill them out for the bolts. Is this going to be a big job? Looks like it could be done with a drimmel tool. Is there anything that needs to be watched out for when installing these? I am going to have my old ones repaired, but it would be nice to have the knots 2 u pants bolted up to these new ones and painted all at the same time.
