I have a 37 ford axle and am using model A bones. In fitting the wishbone yokes to the axle, they are so tight that I either need to enlarge the distance between the yoke ears or file the perch boss slightly to get the yoke to slip over. Is this common?
According to Sid's chart both should have 2-1/4 inch spring perch bosses Ford Dropped Axles | Nostalgia Sid's | Custom Axle Alterations Are both exactly 2-1/4? I'd be inclined to think someone tweaked the bones at some time or other.
They are both 2 1/4. I managed to use a big drift and got them close. I think it will work out. I think the yokes were slightly tweaked. I spread them slightly and got them started. The drift did the rest. Thanks
