thanks for the info guys, i saw a few 46s at a car show last weekend and it looks like from 41 and on they started bolting the fenders thru the cowl. i think the cabs were all mounted the same from 39 to 46. i might try bolting them to the cab with a 1/4 rubber spacer between fender and cab slid on the bolt. the gap i have on the passenger side is just to big to leave it as is.
