Is the original rod bent? If not you can most likely get the tie rod ends off the existing rod by cutting the bolts off with a hack saw (if you can’t coax them off with penetrant, heat or both) and as 52Carl suggested, use a cold chisel in the the slot to expand the thread. Use some penetrating oil to help break the rust bond. I used that same procedure on my ‘52 and was able to save the parts and just install the rebuild kit. They were pretty crusty but after cleaning and painting looked new.
