I've been working on this sweep also. Turns out I ordered sweeps from 2 different suppliers, not knowing I all ready had a set tucked away. I was surprised to discover both are different configurations/shapes.
One is T-shaped and the other one is a J-shape.
Now I'm trying to figure out which is correct for a '48 3100.
Thanks
Jeff
Where did you get the J shape one? On my last truck I had extreme difficulty installing the T shape. Looks like the J would fit better.
