I'm fitting a CE 47" beam to split '40 bones. The plain pins I had from Speedway fit the bones okay but are larger than the CE axle perch holes and won't go through. The axle is right around .620" and the meat of the pin is just shy of .670". Before I go looking for the right pin, if one exists,I'd like to know whether the axle is wrong or the pin I have is wrong. I can turn the pins down to go through the axle as the tapered head and tapered bottom washer do the locating but I'm just curious what the mismatch stems from. Any thoughts?
