OK let me put it this way. I'll put my $$$ where my mouth is, I'll take 3 at $150.00 each as long as the factory hood and side panels will fit like OEM and as long as it looks like the OEM grill. That said consider that most of these tractor are now around 20 years old and are now just getting to the point that the factory plastic is getting tired do you think it's a good investment to redesign them into a metal replacement? Just speaking from my own experience the hoods seem to last pretty well, the pins on the side panels are the next to go but the mounting points on the grill shell seems to be the worst area. Not trying to talk you out of doing this but I'm not sure the market exists to make it financially viable.
This is what you can buy a new plastic grill for today.
