That's what I was going to say. I'm a fan of people making 70s into GLs if it means more good 70 fenders in circulation!If you change the front clip to a 69, I would be interested in the 70 front clip if you decide to sell it all.
That's actually how I got my 70 fenders last year. A young guy in Kentucky was redoing his 70 into a 69 front end! God bless him!
