Re: HELP... 1951 3100 fr. Frame rail hole pics.

This is weld on but the centerline of the axle is still the same 18-1/8 inches back from the center of the hole that the spring shackle goes though.

Speedway instructions that are pretty detailed https://static.speedwaymotors.com/pdf/91044754.pdf



One thing. don't get stupid and remove those cast pieces that the spring shackles went though in the name of "cleaning up the frame horns. Those are what aligns the front bumper brackets right and if you remove them you have a heck of a time getting the bumper lined up right.
