I have/had two complete headlight/battery box inner wing units cut out of a scrap disco, and replaced the whole corner from the edge of the rad/intercooler to the front turret where the shocker is, this included the front mount too, just unbolted the old mount and it cut awau with the complete wing unit, and rebolted the replacement in then lined everything up and welded the unit back in
You could do a smaller type job, depending on the state of the surrounding metal
