Most modern rods have a smooth machined bore for the bushing --a pressed in bushing has good contact with the rod ---the Ford rods have a much more coarse machined surface ---to have the bushings stay in and fit properly they need to be "burnished" to swell the bushing into the valleys --if you take them to a machine shop make sure they understand this, another way to do it is with a ball bearing pressed through ther pin hole to force the bushing to conform to the machined surface ---as Ol Ron says sometimes it is best left as is ---trying to replace them can come out worse, for all the work many times a NOS rod is cheaper, and a set in the box can be very close in weight --I just bought a set at Hershey, all the rods are within 1 gram end for end, and total weight varied by less than 1 gram and it would have cost well over the 100$ I spent to make old rods that close
