After riving my F1 on wet roads this week, think you will be happy to have that 100 lbs on the back when you aren't carrying any loads!
I'm finding Bonus Built Trucks to be very "mis understood." They look huge, but mine is actuallu shorter and narrower than my 2002 Ranger. It's also not as heavy in the rear end and when I hit the brakes on it onthe wet road, those supposedly "weak" brakes locked up fine and m litle light F1 slid on it's new wide radials!
Anyway, your work looks great....any more thought to the back light arrangement (I remember your previous post)?
