Looking to get front end weight down.

I wonder what those weigh.
With them gone, to what will you bolt the fenders, to keep them from going AWOL at speed? If they go, what's to stop the grill and maybe the hood from also deserting?
If you put some tubing back in to hold everything together........ To me it seems like a lotta work for a few pounds, that your 470 will never appreciate. but what do I know, I'm no racer for a reason,lol.
