That's the good crack,leave it alone.:thumbsup:
A chassis cracked like that used to be outlawed in some racing circles,as the car usually got better when it cracked lengthwise.
In other words if it ain't bothering you,it probably isn't bothering the car either:wave:
You might want to try putting small pins into the pick-up shoe tab's ,as they had a habit of breaking off on the early G's.
If you drill a small hole lengthwise into the tab,and insert a small piece of piano wire into the hole,it'll do wonders for keeping the tabs from breaking.
If i remember right,i use to drill the tabs with a .015" drill bit,and then inserted a short length of .015" piano wire into the hole,i've also done them with .020" piano and apporiate bit.
Drill them by hand,as the plastic tab drills very easy if you use a new sharp bit
